Time is possibly the most fascinating construct devised by humans. You may say that all organic entities have a ‘biological clock’ and act accordingly. And you might ask, what’s so special about time. It’s true that animals and plants seem to operate to built-in clocks. But humans are unique in the way that we have consciously embraced the notion of time and in the way we let our perception of time dictate how we lead our lives. A while back, I had written about ‘The Secret Powers of Time and Regret.’ You might want to check this out either before or after reading further.
What is time?
Time, at its core, is an artificial and abstract concept. In practice, it’s about keeping track of change and the patterns by which change manifests itself. Time is about keeping track of changes in ourselves and in the world around us. And this has become deeply embedded into our psyches, and into our religions and philosophies. The early human, for instance, must have noticed the regularity with which dawn broke and the sun set, and subliminally internalized the notion of time while deriving benefits of recognizing such patterns. One thing must have led to another, and eventually resulted in Egyptian and Greek sun dials, Indian hour glasses, Swiss clocks , Julian calendars and other inventions which helped in accurate measurement of and tracking time.
If there was no change or observable patterns either in ourselves or in the world around us, we would have simply ignored the passage of time. In other words, our mortal existences are so absurdly short that we have come to believe that there is a necessity to keep track of and measure time. There is no other entity (that we know of) in the universe which consciously does this and allows the concept of time to dictate its behavior.
Imagine if each of us were to live for a few million years before dying. During the course of our lives, we would observe hills being formed, rivers changing courses and weather patterns changing so gradually that it’s possible that we might not value the notion of time or the practice of measuring it at all. I wonder how the absence of the notion of time would influence the way we live our lives. Let’s take this to one logical extreme: Suppose we were all to be immortal, wouldn’t we simply discard time since it would cease to have any value? So, could the converse be true? If we ceased to value time, would that be our ticket to immortality? Interestingly enough, that’s what eastern wisdom tells us – to stay in the now and discard all perceptions of time such as the past and the future. I told you that this was fascinating stuff.
There’s a lot to write on this. I’ll stick to what enthralls me about the way we and our religions have looked at time.
Abra’amaic religions – Judaism, Christianity and Islam – take a linear view of time. They agree that the world started with the creation of the universe by God, who also created the first man and woman roughly five thousand years back. They have neatly compartmentalized time into the beginning - when God created man and woman, now - while we are alive, and the everafter, the future that comes after death when we shall receive Judgment and live in eternal bliss or torment depending on the way we led our lives. The simplicity of this compartmentalization is attractive. It provides a sense of purpose, which is to conduct our affairs now in a manner that we shall be one of God’s chosen ones in the future. It provides a basis in the past – which is that God created man five thousand years back.
Time is accorded a great deal of importance in these religious schools, which borrowed the Greek notion of time being finite and running out . This life that we have now is our only chance of getting it right. Once we die, our time ends, and so do our chances of correcting the errors of our ways. Seize the day and the life you have been given, they say. This simplicity is so powerfully compelling and so easy to grasp that it has taken roots in the way we’ve divided our history timeline – in terms of what happened before the birth of Jesus Christ (Before Christ – B.C.) and that which is happening in the year of our Lord (Anno Domini – A.D.).
Eastern schools are, in contrast, vexingly vague about time. They insist that time is illusory and hence without value, and all that matters is this mysterious thing called “now.” They candidly confess that they don’t know when and where it all began, and who started this whole thing called the universe. They tell us that we’re trapped in a web of illusion called maya, and that time is merely one of the illusory constructs which perpetuates maya. They ask – if nothing exists and everything is an illusion, then how can the concept of time be relevant? They tell us that if we can manage to find and stay in the moment, then time itself will cease to exist, and the past, present and future will merge into one and we will be able to see them simultaneously. Indeed, the Sakyamuni was believed to possess the powers of rising above time and view all his past lives, the stories of which came to be known as the Hitopadesha.
This is all confusing and perplexing, and intoxicating and exhilarating at the same time. We listen in fascination each time, and then go away, shaking our heads, back into our worlds in which time only moves forward linearly. We don’t know what to make of such theories, or what to do about them. The eastern concept of timelessness applies temporary balm on our wounded souls and scarred pysches, and provides us with some indescribable comfort. It soothes us to hear that time does not run out and that we will have more chances to get things right, and that God and this universe may not be as harsh and unforgiving as they are made out to be.
A close-up look at Hindu cosmology, calendars and time scales
Carl Sagan describes the Big Bang and the creation of the universe in his television series “Cosmos,” which first aired when I was in school. In this, he talks about how it all began according to science, and how the universe formed within the first new nano seconds of the Big Bang. In the world of science, creation is synonymous with the formation of matter and the creation of space and time.
In “Cosmos,” Sagan makes an interesting observation about how Hinduism has looked at time. He says, ” <snip> a wonderful aspect of Hindu cosmology is that it is consonant with that of modern scientific cosmology. We know that the Earth is about 4.6 billion years old, and the cosmos, or at least its present incarnation, is something like 10 or 20 billion years old. The Hindu tradition has a day and night of Brahma in this range, somewhere in the region of 8.4 billion years. As far as I know. It is the only ancient religious tradition on the Earth which talks about the right time-scale.“
Precisely for its uncanny resemblance to modern scientific cosmological time scales, I figured it would be interesting to share my understanding of the Hindu view of the age of the universe. These details are partly from my notes from reading Srimad Bhaagavatam and heavily borrowed from more erudite persons (my sisters), all of which can, I am sure, be found on Wikipedia.
Note: I’m not writing this to prove the superiority of the Hindu view vis-a-vis other religious views. I have no interest in such matters. Each religion brings forth its own compelling insight. That is the raison d’etre of each religion. To bring forth new insights and comfort. In the matter of cosmology and universal time scales, the Hindus have put forth a grand idea, and whether true or not, it does make the pulse quicken. My belief is that it would benefit all to take notice of this.
How old is the universe according to Hindu cosmology?
The Hindu cosmic cycle is divided into Yugas, Chatur or Maha Yugas and Kalpas.
A ‘basic’ cycle is called a ‘Yuga‘ or an ‘age’. There are four such Yugas, each for a different tenure. These Yugas are Krita or Satya Yuga, Treta Yuga, Dwapara Yuga and Kali Yuga. Their durations are (in human years):
Krita Yuga: 1,728,000 years. Treta Yuga: 1,296,000 years. Dwapara Yuga: 864,000 years. Kali Yuga: 432,000 years.
Note: At the end of each Yuga, the earth is overwhelmed by elements and humans are wiped out. Each Yuga is followed by an interlude of still and nothingness and life begins anew in the next Yuga.
Each quartet, a set of 4 Yugas, is called a Maha Yuga or a Chatur Yuga.
1 Maha Yuga = One quartet of 4 Yugas = sum of (Krita + Treta + Dwapara + Kali + all interludes between them) = 4,320,000 years = 4.32 million years.
1 Kalpa = 1,000 Maha Yugas = One half of a day of Brahma, the creator = 4.32 billion years.
1. Each Kalpa is successively ruled by 14 Manus. Each reigning period of a Manu, the giver of Dharma, is 71.42 Maha Yugas. So, Manus come and go during the tenure of a Brahma.
2. Brahma is the creator of the universe, filled with its stars, planets and moons and Manus who reign periodically over it. Brahma is considered to be a manifestation of the (Para) Brahman, the or spirit underlying the universe which binds all things and is the fundamental energy that makes the cosmic dance possible. Even Brahma, the creator, cedes his place and “dies,” at the end of his tenure of a 100 years. And a new Brahma is manifested by the Para Brahman, and the cycle goes on. Such is the nature of the universe, according to the Hindus, one in which permanence is assured to none.
So, what do we get?
When we put the time lines together, we get -
A “full day” ie “day” + “night” of a Brahma works out to ( 2 x half-day of Brahma or 2 x Kalpa) = 2 x 4.32 billion = 8.64 billion years.
This number is interesting because cosmologists now believe that the Big Bang happened roughly 13 billion years back (revised significantly since Sagan did Cosmos twenty five years back). This number of 13 billion years is of the same magnitude (proportionally) to what the Hindus postulated many moons ago. This aspect of Rig Veda is nothing short of spellbinding. How could have they come up with such a grand scale – in billions of years – for the cosmological age of the universe? What kind of minds and awareness did they possess to get into the same ballpark timeline wise, when it has taken us billions of dollars worth of equipment and painstaking scientific research to get into the same ball park? Was it a lucky guess or is there more to this than meets the eye? Incredible.
What’s even more incredible is that the Hindus didn’t restrict themselves to the current universe. The Rig Veda tells us that the life of the cosmos stretches endlessly before the Big Bang and will stretch endlessly well after the current version of the universe ends. The life of a Brahma, we’re told, is 100 years of 360 days each, where each day = 8.64 billion years. Simple math (100 x 360 x 8.64 billion) gives us the life time of Brahma, which is the life of the cosmos. This number is a staggering 311 trillion years. And after 311 trillion years, the ‘old’ Brahma ‘dies’, and a ‘new’ Brahma is ‘born’. And the cycle of 311 trillion years repeats itself with a new Brahma, endlessly into time. Mind boggling!
The Sankalpa mantra: Where in the world are we? And what time is it now?
If you’re Hindu or if you’ve observed Hindu rituals, you may have heard a set of mantras called the Sankalpa mantra which precedes Hindu rituals. The Sankalpa mantra is meant to keep track of where we are, and the time it is now in this version of the cosmos that we exist, at the time of performing the said ritual.
A brief context first to the Sankalpa mantra
It is said that we are presently in the Sveta-Varaha kalpa in the reigning period of Vaivaswatha – the 7th Manu. In this Manvantara we are in the 28th Maha Yuga. As per Hindu cosmology, Brahma is supposed to have completed 50 Brahma years and is now in his 51st year. For this reason, he is called “Parardha-dvaya-jivin” ie he now lives in the second half of his life. The word ‘parardha’ means half. So Brahma is called this as he has completed one half of his life. This might help you make better sense when you hear or read about the Sankalpa. On a lighter note, we live in a time when our Brahma has reached middle age, and one can only hope that he doesn’t go through a mid-life crisis
As for the Sankalpa mantra, it goes roughly as follows-
…. dvi-teeya parardhe: In the second half of Brahma’s life
Sveta-varaha kalpe: in the kalpa of Sveta-Varaha
Vaivaswatha manvantare – in the reigning period of the Vaivaswatha Manu
Ashta Vimsati tame: In the 28th Maha Yuga of the current Manvantara
Kaliyuge: in this Kali Yuga
Prathame Padhe: In the first quarter of this Kali Yuga. Note: Kali Yuga is said to have started in 3102 BC according to Aryabhatta.
Jamboodveepe: This denotes the place where the ritual is being performed. Note: India was once believed to have been an island called Jambudveepa.
Bhaarata Varshe, Bharata Kande: in this land called Bhaarata.
Sakhabde Mero, Dakshine Parsve: to the South of the Meru mountain. Note: Mount Meru is repeatedly referenced in Hindu purana, and is believed to have existed when India was once an island.
Asmin Varthamane Vyavaharike: in the current period now reigning
Prabhavadi Shasti Samvatsaranam Madya: which is in the middle of a cycle of 60 years starting from the year Prabhava. Note: Hindu calendar was divided into sixty calendar years, each with a name to itself, the first of which is called Prabhava.
< insert name of year > Nama Samvatsare: the name of the present year in the 60 year Hindu calendar. Note: The present year is called Nandana.
<fill in> ayane: Dakshin-ayane (when the sun travels south) or Uttar-ayane (when the sun travels north). Note: Uttarayana is the period between the winter and the summer solstices (roughly Dec 22 to June 21) and Dakshinayana is the other half of the year.
<fill in> ritou: Ritou denotes the six seasons or Ritus, who are Vasantha, Greeshma, Varsha, Sharadh, Hemantha and Shishira
<fill in> Maase: One of the 12 Tamil months when performed in Tamil tradition.
<fill in> Pakshe: Either Shukla Paksham (day after Amavasya to and including Pournami) or Krishna Paksham (day after Pournami to and including Amavasya)
<fill in> Subha Thithou: Name of the day of the month, which is one of the 15 days between Pournami and Amavasya. These are Prathama, Dvithiya, Trithiya, Chaturthi, Panchami, Shasti, Saptami, Ashtami, Navami, Dasami, Ekadasi, Dwadashi, Trayodasi, Chaturdasi, Pournami and Amavasya.
<fill in>Vaasara Yuktaa-yaam: Name of the day of the week, one of Bhanu, Soma, Bhowma, Soumya, Guru, Brugu and Sthira
<fill in> Nakshatra Yuktaa-yaam: Name of the Nakshatra or star prevalent on the day.
Upon reciting all of the above, the name of the ritual is said. According to HH Sri Paramacharya of Kanchi Kamakoti, the Sankalpam is a record of the ritual one performs with exact details going down to the day and location of the ritual. Presumably, this was an effective technique of keeping records and track of time in a tradition that relied more on word of mouth than writing things down.
There is another unusual feature of the Hindu calendar. Each year is labeled by the number of years elapsed since the epoch. As of 2012, 5114 years have elapsed in the Hindu calendar. The present epoch (Kali Yuga) is believed to have started on February 18, 3102 BC (though there are debates around this).
What boggles my mind is the ‘how did these guys keep track of everything?’ question. If the earth and the universe are being destroyed and rebuilt every so often, how do the Hindus confidently state that we are in the 51st year of Brahma? How did the information about the previous epochs get transferred across the epochs? The Hindu calendar is so precisely documented that they have every Manu in every epoch documented going all the way back to the beginning of the life of Brahma himself. How is this even possible? Should we dismiss this as carefully planned deception and bunkum? If it is deception, why would anyone go to such trouble to plan such elaborate deception when easier routes are available?
There is something inspiring about the way we humans have looked at time, especially those in the Vedic tradition. The next time you observe or perform a ritual, hopefully I have made it a more interesting exercise for us. Hopefully, it will make you wonder about the grand scale of this amazing universe and its life time, our own insignificance in the scheme of things that are destined till the end of time and the transcendent beauty of the nature of enquiry itself.
Let me wind up for now, with another quote from Carl Sagan on Hindu cosmology:
“The Hindu religion is the only one of the world’s great faiths dedicated to the idea that the Cosmos itself undergoes an immense, indeed an infinite, number of deaths and rebirths. It is the only religion in which the time scales correspond, to those of modern scientific cosmology. Its cycles run from our ordinary day and night to a day and night of Brahma, 8.64 billion years long. Longer than the age of the Earth or the Sun and about half the time since the Big Bang. And there are much longer time scales still.”
PS: For a topic as complex as this, I’d be surprised if there were no errors in the way I’ve understood things. I stand by, ready to correct errors and mis-statements. Do write and let me know if you see anything amiss. Thanks.
