Incredible Details of the 26-Million-Year Cycle of Mass Extinctions Recorded in Ancient Vedic Texts

The idea that human civilization has been gradually evolving over time in a linear manner, is a relatively new concept that was formulated during the period of colonization. Nearly every ancient culture believed otherwise. They said that time moves in cycles, smaller and larger, and that our civilization has gone through innumerable ups and downs over eons. With the emergence of new scientific data, it is becoming increasingly obvious that the ancients knew what they were talking about, and we have been far too quick to denounce the collective wisdom of our ancestors as the flights of fancy of primitives.

The concept of the Yuga Cycle or the Great Year was known to most ancient cultures, and, as per this framework, we have devolved from an erstwhile Golden Age of illumination, harmony and abundance to the current age of greed and lies, discord and scarcity. The fundamental factor that differentiates a higher age from a lower one is the state of man’s consciousness. In a Golden Age, consciousness is so elevated and purified, that we can easily comprehend the mysteries of creation, and of our place in the wider scheme of things, and, thus, we are able to lead long lives in a state of joy, balance and harmony. Since the environment reflects our state of consciousness, there is fertility and abundance in the higher ages and a lack of diseases and natural disasters. But as we devolve along the descending arc of the Yuga Cycle or Great Year, we move from soul consciousness to ego consciousness, accompanied by a degradation in our physical size and the external environment, which gradually leads to a burgeoning of violence, misery and discontent in society.   

What is really striking is that all of these claims are now being borne out by scientific findings from different disciplines. It turns out that, over the past 12,000 years of the descending arc of the Yuga Cycle, humans have shrunk in size by at least 10%, along with a corresponding decline in bone strength and athleticism. This has been accompanied by a 10% to 17% reduction in our cranial volume over the same period, which has not only diminished the average intellect but reduced our memory and atrophied our sense of judgment and morality, along with a host of subtle mental abilities such as foresight, telepathy etc. And to add to these surprising statistics, it turns out that, towards the end of the last Ice Age, there was no food scarcity or diseases, but as time went on, food sources became scarce, many kinds of diseases became endemic, and incidences of violent deaths increased substantially. 

Everything that the ancients said about the Yuga Cycle or Great Year is now turning out to be facts, but why aren’t these statistics being discussed on mainstream media outlets? It’s because they run counter to the Darwinian myth of gradual evolution by natural selection that has been literally shoved down our throats and turned into an incontrovertible dogma. Very few scientists, academics or media channels will dare to question Darwinism, for fear of getting ridiculed, denied funds or promotions, or even hounded out of their profession. Do not question the science, is the current science. This, unfortunately, is the insidious manner in which things work in the Kali Yuga, the darkest age of human history. 

In my book, Yuga Shift, I have presented what I believe is the original Yuga Cycle framework. It is of the same duration as the precessional cycle of the earth, i.e. 25,800 years, and comprises an ascending cycle of consciousness and a descending cycle of consciousness, which are separated by two extended periods of transition that the Greeks called Kataklysmos (meaning “Deluge”) or the “great winter” of the Great Year, and Ekpyrosis (meaning “Conflagration”) or the “great summer” of the Great Year.

It is the period of Ekpyrosis that we are heading towards, as the Kali Yuga and the entire descending cycle of consciousness come to an end in 2025.

A Day and Night of Brahma

One of the thoughts that come to mind when we think about the Yuga Cycle or the Cycle of the Ages is that, does it continue indefinitely, without any beginning or end, or is it part of an even larger cycle of time. 

As per the ancient Vedic texts, there is an even longer cycle of time called the “Day and Night of Brahma”, which extends for a whopping 25.8 million years! It consists of a “Day of Brahma” which extends for a thousand Yuga half-cycles of 12,900 years each, adding up to 12.9 million years. A “Day of Brahma” is followed by a “Night of Brahma” of equal duration. This cycle has been described in a number of texts.

As per the Vishnu Purana, at the beginning of a “Day of Brahma”, the world is created from unmanifested matter by Brahma, who is the pure, eternal, formless, consciousness, seated at the navel of the world. At the end of a “Day of Brahma”, the entire creation is destroyed and turns into a mighty, formless ocean. This is followed by a “Night of Brahma” when no life forms exist. The creative process begins once again at the beginning of the next “Day of Brahma”.

“At the end of this day (i.e. “Day of Brahma”) a dissolution of the universe occurs, when all the three worlds, earth, and the regions of space, are consumed with fire…When the-three worlds are but one mighty ocean, Brahma…satiate with the demolition of the universe, sleeps upon his serpent-bed…for a night of equal duration with his day (i.e. Night of Brahma); at the close of which he creates anew.”[1] 

In the Bhagavad Gita, Lord Krishna provides a specific value for the duration of the “Day and Night of Brahma”. 

“Those who understand the cosmic laws know that the Day of Brahma ends after a thousand Yugas and the Night of Brahma ends after a thousand Yugas. When the Day of Brahma dawns, forms are brought forth from the Unmanifest; when the Night of Brahma comes, these forms merge in the Formless again. This multitude of beings is created and destroyed again and again in the succeeding days and nights of Brahma.”[2]

It should be remembered here that, when the Sanskrit texts talk of the Yuga Cycle, they mean the Yuga half-cycle, which goes from Satya Yuga -> Treta Yuga -> Dwapara Yuga -> Kali Yuga, including the periods of transition between them. A 1000 Yuga half-cycles is equivalent to 500 complete Yuga Cycles of 25,800 years each, which works out to 12.9 million years.

A “Day of Brahma”, therefore, extends for 12.9 million years, during which time we experience a long sequence of 500 complete Yuga Cycles, and the earth is bustling with life and civilization. It is followed by a “Night of Brahma” of equal duration of 12.9 million years, when all life is snuffed out, and the entire world exits as a giant, formless, lifeless ocean. Thus, the “Day and Night of Brahma” is a grand cosmic cycle of creation and dissolution spanning over of 25.8 million years.

It is easy to see that the time period between two successive dissolution events in this cycle is 25.8 million years, which can be rounded off to 26 million years. Now, if a dissolution of life on a cosmic scale occurs every 26 million years, shouldn’t this fact be reflected in the fossil records of our planet? 

Amazingly enough, this is exactly what has been indicated by recent paleontological evidence: every 26 million years there is a mass extinction of species on the earth!

Mass Extinction Cycle

Around 67 million years ago, the earth looked like a very different place. Enormous dinosaurs stalked the landscape, while massive avian reptiles patrolled the skies. But, then, something catastrophic happened, which changed things almost overnight. Nearly 66 million years ago the earth went through a period of rapid death, called a mass extinction, when more than 75% of all animal and plant species became extinct. Scientists now have evidence that the die-off was caused when an asteroid, about 10 kilometers in diameter, struck the earth at a speed of about 20 km/sec and created the 200-km wide Chicxulub Crater in southeastern Mexico, releasing a billion times more energy than the atomic bombs dropped on Hiroshima.

The impact generated hot winds and shock waves, and ejected a gigantic jet of molten material, several times hotter than the surface of the sun, which set fire to everything within a thousand miles. Measurements of the layer of ash and soot that eventually coated the Earth indicate that fires consumed about seventy percent of the world’s forests. The collision triggered powerful earthquakes and spawned mega tsunamis, hundreds of feet tall. A model of the impact event developed by scientists at Los Alamos National Laboratory shows,

“The dust and soot from the impact and the conflagrations prevented all sunlight from reaching the planet’s surface for months. Photosynthesis all but stopped, killing most of the plant life... After the fires died down, Earth plunged into a period of cold, perhaps even a deep freeze. Earth’s two essential food chains, in the sea and on land, collapsed. About seventy-five percent of all species went extinct. More than 99.9999 percent of all living organisms on Earth died, and the carbon cycle came to a halt.”[3]

It is to be noted here that the impact event at the K-T boundary effectively killed off all the living organisms on our planet, even though the species die-off is estimated at roughly 75%. This is because some of the species that existed at that time, re-appeared in the fossil records at a later date, and therefore, is not considered to have gone extinct. 

The fiery cataclysm that led to the extinction of the dinosaurs is in perfect alignment with the description of the dissolution event that occurs at the end of a “Day of Brahma” when all life forms on the earth are destroyed, and, as the Vishnu Purana states, “all the three worlds, earth, and the regions of space are consumed with fire”. Admittedly, the ancient Vedic sages knew a thing or two about the true history of our planet.

Moreover, this is not the only mass extinction event that has occurred on our planet in the past. There are many more, and, quite surprisingly, they occur in a cyclical manner every 26 million years!

In 1984, paleontologists David Raup and Jack Sepkoski of the University of Chicago identified a 26-million-year periodicity in extinction rates over the past 250 million years.[4] As part of a broad study of the distribution of marine life through geologic time, Sepkoski had prepared a listing of about a quarter of a million species of sea-dwelling creatures, both extinct and current, noting the point in time where they appeared and became extinct. The study was confined to marine organisms since the chances of finding fossils are much higher under the sea. The oceans are areas of net sedimentation, whereas land is an area of net erosion. 

David Raup, a senior colleague at the University of Chicago, suggested to Sepkoski that he examine the list for any evidence of a pattern in the timing of the mass extinctions. Sepkoski decided to concentrate on the last 250 million years of geologic time and throw out animals whose exact timing of appearance and disappearance were debated. He was left with about 500 of his original 3,500 marine families (250,000 species). Sepkoski put the data through a computer program and was surprised to find that life forms on Earth disappeared in great numbers every 26 million years. Both of them checked for errors and confirmed the pattern; life seemed to disappear drastically exactly every 26 million years. In their seminal paper, Raup and Sepkoski wrote:

“The temporal distribution of the major extinctions over the past 250 million years has been investigated statistically using various forms of time series analysis. The analyzed record is based on variation in extinction intensity for fossil families of marine vertebrates, invertebrates, and protozoans, and contains 12 extinction events. The 12 events show a statistically significant periodicity (P <0.01) with a mean interval between events of 26 million years. Two of the events coincide with extinctions that have been previously linked to meteorite impacts (terminal Cretaceous and late Eocene). Although the causes of the periodicity are unknown, it is possible that they are related to extraterrestrial forces (solar, solar system, or galactic.)”

The mass extinction events are not selective at all, in the way Darwin had proposed. As per Darwinism, the evolutionary process is gradual, and life forms evolve slowly through a process of natural selection, in which the inferior life forms are eliminated since they are less suited to the struggle for existence. However, in case of a mass extinction, there is no way of knowing beforehand which species will survive the extinction event and which will die out. The process is entirely random. In a paper titled, “The Role of Extinction in Evolution” (1982), David Raup wrote,

“The largest mass extinctions produce major restructuring of the biosphere wherein some successful groups are eliminated, allowing previously minor groups to expand and diversify…There is little evidence that extinction is selective in the positive sense argued by Darwin. It has generally been impossible to predict, before the fact, which species will be victims of an extinction event.”[5]

The 26-million-year extinction cycle has, since then, been validated by a number of independent studies. In 2010, Adrian Melott and Richard Bambach identified a 27 Myr periodicity in the extinction data, extending over the past 500 million years. They wrote,

“We examined periodicities in extinction over the last 500 million years, and concluded that a signal detected by Raup & Sepkoski (1984) was present in better resolved, more extensive current data, over a longer time period than they had originally claimed, and at a higher level of significance. The claimed period grew from 26 to 27 Myr, and is also now observed to extend over the entire 500 million years interval rather than just the last 250 million years, due to revisions in the geological timescale since the 1980s.”[6]

Mass Extinctions and Impact Craters

It has become quite obvious over time that the primary triggers for the mass extinctions are impact events. In 1980, the father-son duo of the Nobel Prize-winning physicist Luis Alvarez and his son, the geologist Walter Alvarez, had inferred that the sudden extinction of dinosaurs at the K-T (Cretaceous–Tertiary) boundary, nearly 66 million years ago, was due to the impact of a large asteroid or comet. 

Luis and Walter Alvarez had noticed that sedimentary layers all over the world at the K-T boundary contain a concentration of iridium many times greater than normal. Iridium is extremely rare in the Earth's crust but is abundant in chondritic meteorites and asteroids. Moreover, the isotopic ratio of iridium in asteroids is similar to that seen in the K–T boundary layer. Based on this, the Alvarez team suggested that the iridium spike at the K-T boundary was of extraterrestrial origin and had settled out of a global dust cloud triggered by the impact of an asteroid, at least 10 km in diameter.

While Alvarez’s theory was initially rejected by most paleontologists, the subsequent discovery and dating of the Chicxulub Crater in Mexico validated their findings and silenced the dissenters.

Since then, other scientists have found that the estimated ages of a number of impact craters coincide with the mass extinction events.

In the mid-1980s, cratering specialist Richard Grieve ran his list of well-dated impact craters through the computer at NASA’s Goddard Institute for Space Studies and identified a crater periodicity of nearly 30 million years. Around the same time, Walter Alvarez and Richard Muller at UC Berkeley identified a 28 million-year cycle using a somewhat different set of craters. 

In 2015, Michael Rampino and his student Ken Caldeira studied more impact craters with improved crater-age data, and “found that craters and extinctions both seem to occur with the same 26 million-year cycle”.[7] Crater formation rate peaks close to the time of an extinction event, and some of the largest impact craters were formed during an extinction event. Clearly, the 26 million-year extinction cycle is a significant geological signal, which some scientists call the “geological heartbeat” of our planet. 

It is nothing short of astonishing that, such precise information about the 26-million-year mass extinction cycle has been specified in the Vedic texts. Of course, a couple of questions still need to be clarified. The Vedic doctrine claims that the earth remains entirely devoid of all life forms for the entire 12.9-million-year duration of the “Night of Brahma” that follows the extinction event. Do have any scientific evidence in support of this? As it turns out, there is. And more studies are arriving at the same conclusion.

The Night of Brahma

In May 2012, an article in Nature Geoscience written by Dr. Zhong-Qiang Chen of the China University of Geosciences in Wuhan and Professor Michael Benton of the University of Bristol stated that it took nearly 10 million years for life forms to appear after the end-Permian mass extinction event 250 million years ago, which had wiped out nearly 90% of all living species.[8]

As per the scientists, two factors could have delayed the appearance of new life forms: 1) the sheer intensity of the crisis, and 2) the continuing grim conditions on earth after the first wave of extinction.[9] Professor Michael Benton wrote that “in this most devastating case, life did recover, after many millions of years, and new groups emerged. The event had re-set evolution.”[10]

Another study conducted in 2019 found that it takes at least ten million years before the diversity of a species achieves a similar level to that seen before the mass extinction event.[11] Dr. Lowery and Dr. Fraass studied foram fossils for a time period covering roughly 20 million years, from the end of the Cretaceous mass extinction (66 million years ago) and extending through the ensuing recovery, to determine how long it took these minibeasts to recover their species diversity. Dr. Lowery and Dr. Fraass concluded that it took at least ten million years for foram species diversity to recover.[12]

These studies confirm that, in general, it takes around 10 million years or more for life forms to emerge and global biodiversity to recover, after a mass extinction event. This confirms what Vedic sages said about the “Night of Brahma” being a time when the earth is devoid of life forms.

The other question that was on my mind is this: As per the Vedic doctrine, life forms arise very quickly after a “Night of Brahma” ends, and the next “Day of Brahma” begins. Now, does this really happen? Do we see a sudden emergence of life forms after a mass extinction event, or do they appear gradually through a process of natural selection extending over millions of years, as Darwin had proposed?

Punctuated Equilibrium

Darwin’s theory that new species arise by the slow and steady transformation of entire populations is not reflected in the fossil records. If this were true, then a continuous sequence of “intermediate forms”, showing incremental changes on the way to a new species, should have been found in the rock strata. Unfortunately, intermediate forms connecting species have never been identified. The absence of “missing links” had also concerned Darwin, who attributed it to the imperfections of the geological record. In the Origin of Species, Darwin wrote, 

“Why then is not every geological formation and every stratum full of such intermediate links? Geology assuredly does not reveal any such finely graduated organic chain; and this, perhaps, is the most obvious and gravest objection which can be urged against my theory.”[13]

“The geological record is extremely imperfect and this fact will to a large extent explain why we do not find interminable varieties, connecting together all the extinct and existing forms of life by the finest graduated steps. He who rejects these views on the nature of the geological record will rightly reject my whole theory. ”[14]

In 1972, Harvard University paleontologists Stephen Jay Gould and Niles Eldredge wrote their seminal paper titled, “Punctuated Equilibria: an alternative to phyletic gradualism”, in which they argued that the fossil record is not imperfect, as claimed by Darwinists. The many breaks in the fossil records are real, and they express how evolution occurs. The absence of transitional forms implies that evolution does not occur by the slow and gradual transformation of a species.   

“Under the influence of phyletic gradualism, the rarity of transitional series remains as our persistent bugbear…Many breaks in the fossil record are real; they express the way in which evolution occurs, not the fragments of an imperfect record. The sharp break in a local column accurately records what happened in that area through time.”[15]

“Although phyletic gradualism prevails as a picture for the origin of new species in paleontology, very few classic examples purport to document it. A few authors have offered a simple a literal interpretation of this situation: in-situ, gradual, progressive evolutionary change is a rare phenomenon. But we usually explain the paucity of cases by a nearly ritualized invocation of the inadequacy of the fossil record.”[16]

Gould and Eldredge proposed the theory of Punctuated Equilibrium to explain what is really happening in the fossil records. They said that the fossil records show long periods of stasis or equilibrium, extending for millions of years, during which time there is little or no evolutionary change, which are punctuated by rapid, episodic periods of speciation, occurring within the space of a few thousand years.

Gould provided further clarification in his article titled, “Evolution’s Erratic Pace (1977)”, in which he wrote that, in any local area, “a species does not arise gradually by the steady transformation of its ancestors; it appears all at once and fully formed”[17]. Once a species appears, it undergoes very little or no evolutionary change for millions of years. Most species, “appear in the fossil record looking much the same as when they disappear; morphological change is usually limited and directionless.”[18]

Gould berated the paleontological community for being so heavily influenced by Darwin’s theory of gradual evolution, that they did not notice the obvious patterns in the fossil records.

“The extreme rarity of transitional forms in the fossil record persists as the trade secret of paleontology…Paleontologists have paid an exorbitant price for Darwin's argument. We fancy ourselves as the only true students of life's history, yet to preserve our favored account of evolution by natural selection we view our data as so bad that we never see the very process we profess to study.”[19]

Gould was one of the most influential and widely read authors of popular science of his generation. He wrote 300 popular essays in the Natural History magazine, for both specialists and non-specialists. In April 2000, the US Library of Congress named him a “Living Legend”. Throughout his career, Gould insisted that the gradualistic models of evolution are simply not reflected in the fossil records, and there is a strong tendency within the scientific community to restrict their thinking within certain belief systems.

In the essay, “Darwin's Untimely Burial” (1976), Gould gave vent to his frustration when he wrote, “I am a strong advocate of the general argument that “truth” as preached by scientists often turns out to be no more than prejudice inspired by prevailing social and political beliefs.”[20]

In “The Return of Hopeful Monsters” (1977), he wrote that, “all paleontologists know that the fossil record contains precious little in the way of intermediate forms; transitions between major groups are characteristically abrupt.” Then, in the essay titled, “Is a New and General Theory of Evolution Emerging?” (1980), Gould reiterated the obvious flaws in the Darwinian model of evolution: 

“The absence of fossil evidence for intermediary stages between major transitions in organic design, indeed our inability, even in our imagination, to construct functional intermediates in many cases, has been a persistent and nagging problem for gradualistic accounts of evolution.”[21]

The truth is that when we go purely by the fossil records – leaving aside all theories and speculations - what we see are rapid bursts of speciation and not the long-drawn-out gradual accumulation of small variations. 

Gould’s Harvard colleague, Niles Eldredge, estimated that the rapid periods of evolutionary change, “took something between 5,000 and 50,000 years—a mere blink of an eye geologically speaking.”[22]

It is equally fascinating that this estimate is very close to the value mentioned in the Surya Siddhanta, which is the oldest astronomical treatise of India. The text states: “One hundred times four hundred and seventy-four years passed while the All-Wise was employed in creating the animate and inanimate creation, plants, stars, gods, demons and the rest.”[23] This means the entire creative process (possibly at the beginning of the current Day of Brahma) took 47,400 years, which falls in the range of values found by Eldredge i.e. between 5000 – 50,000 years.

Oscillations in Morphology

Once speciation is completed, every species remains amazingly stable for millions of years. That does not mean that they do not change at all. In his study of Devonian trilobites, which lived between 380-375 million years ago, Eldredge had found that, once a new species appeared, they persisted for millions of years with very little morphological change. 

“There were some oscillations in morphology, so species weren’t completely invariant, but the net sum of any changes usually tended to cancel out, leading to no net change.”[24]

Gould, by the way, had also found very similar patterns in his studies that focused on fossil land snails from the genus Poecilozonites that lived a few hundred thousand years ago during the Pleistocene.[25]

I was amazed to know of these findings because this is precisely what I had discovered in course of my explorations into the Yuga Cycle. In Yuga Shift, I had proposed, based on ample data points, that, both human cranial volume as well as physical size fluctuates in a sinusoidal manner over a 25,800-year precession cycle, without a net increase or decrease in any direction. I had also written that this oscillation must have been going on over the past 2 million-odd years of human evolution.

And now it turns out that the “oscillations in morphology” occur not only in case of humans, but is a characteristic feature of the entire animal kingdom! All species increase and decrease in size and cranial capacity in a sinusoidal manner over the entire “Day of Brahma” of 12.9 million years, spanning 500 complete Yuga Cycles! This is why the Ice Age megafauna were so much bigger than the animals of today. It’s a recurring pattern of nature.

Every assertion of the Vedic texts with respect to the “Day and Night of Brahma” has now been detected in the fossil records. It is not an approximate correlation, but an almost exact match. Let me recapitulate the important connections:

1. The fossil records show that a mass extinction of species occurs every 26 million years, while the Vedic texts claim that all life on the earth is extinguished at the end of a “Day of Brahma”, every 26 million years. 

2. The fossil records show that it takes 10 million years or more for new life forms to emerge and for global biodiversity to recover, after a mass extinction event. The Vedic texts claim that the earth remains in a lifeless state during the “Night of Brahma”, which extends for 13 million years after an extinction event. 

3. The fossil records show that new species appear in rapid, episodic bursts, in a fully formed state. The rapid speciation events are completed within 5,000 - 50,000 years. The Vedic texts claim that new life forms arise on the earth as soon as a new “Day of Brahma” dawns, and it takes nearly 47,400 years for all living entities to be created.

The fossil records are in perfect alignment with every element of the doctrine of the “Day and Night of Brahma”. This is yet another indication of the profound knowledge of the vast time cycles that our ancestors had possessed, and they passed them down to us in simple verses, although, sometimes they also employed metaphors and symbolic imageries to drive home the point and aid in memorization.

For instance, the events that occur in the course of a “Day and Night of Brahma” have also been metaphorically described as the “breathing in and out of Brahma”. When Brahma breathes out, life forms get dispersed across the cosmos, and when he breathes in, life forms return to the source and the cosmos becomes lifeless. In Yuga Shift, I have proposed that the unmanifested, creative principle, that the Vedic sages called Brahma, refers to the central black hole of the Milky Way galaxy, which, as most scientists agree, acts as the central engine of our galaxy. 

When does the current Day of Brahma end?

In case you are wondering when the current “Day of Brahma” will come to a cataclysmic end, you can rest easy, for it is still a very long way off. The last mass extinction event was the “Middle Miocene Disruption” which occurred around 14.8 Mya (Million years ago). This means that the current “Day of Brahma” started 12.9 Myr later, at around 1.9 Mya. 

Not surprisingly, the earliest fossil remains of the genus Homo (to which our own species Homo sapiens belongs) started appearing around the same time. The oldest hominin fossils are those of Homo habilis, dated to around 1.9 Mya. H. habilis cranial volume fluctuated between 500 cc – 800 cc over the course of its presence in the fossil records till around 1.5 Mya. The bipedal, erect walking, Homo erectus appears in the fossil records from 1.7 Mya till around 250,000 years ago. H. erectus shows a fluctuation in cranial volume between 850 – 1200 cc.

Since the current “Day of Brahma” started around 1.9 Mya, the next cosmic dissolution event is nearly 11.4 million years away. So we can safely take it off our calendar for now. It is not cosmic dissolution that should worry us, but the impending transition out of the Kali Yuga in 2025, which is likely to be very turbulent. 

There is no doubt that our ancestors had a very sophisticated understanding of the vast cycles of time that regulate life and civilization on our planet. Unfortunately, this wisdom was gradually forgotten, as we devolved along the descending arc of the Yuga Cycle. The scientific advances of the past couple of centuries are now helping us to uncover the true significance of these ancient doctrines. However, in general, the attitude of scientists and academics towards the ancient cultures continues to remain dismissive. The problem is that, once we become indoctrinated with a specific belief system since childhood, it becomes extremely difficult to dislodge it, even with the aid of voluminous amounts of scientific data. Unless we adopt an attitude of respect towards the ancient civilizations, we will continue to remain oblivious to the grand stores of wisdom that have been encoded into their sacred texts, symbols and magnificent archaeological monuments.
