Multiple Yugas – Part 1

I would like to spend some of my posts on the excellent topic of "metrics of time measurement" according to Hinduism. Of all the intriguing heritage that we have received from thinkers of ancient India, this is perhaps the most fascinating work.

What is most interesting is that all the possible sources where this topic is discussed - the mythical Puranas like Vishnu Purana, Vayu Purana, the Bhagavatam, along with Bhagavad-gita, literary epics such as Mahabharata and the scholarly works like Surya Siddhanta -- all of them -- agree on the measurements of the duration of yugas, kalpas and so on, with some very minor deviations.

I remember when I had to visit New Delhi once somewhere in the year 1998, Prof. Mohan Apte asked me to go to the Indian National Science Academy on Bahadurshah Zafar Marg and buy a copy of Surya Siddhanta for him if they have one. I was lucky to get one there, and while returning managed to read parts of it, although I could barely grasp any of it.

The Surya Siddhanta is a well-known ancient treatise on Astronomy (composer unknown), which is often cited by later Indian mathematicians and astronomers such as Aryabhatta and Varahamihira. The treatise describes the Hindu time cycles in the first chapter itself, based on which the following calculations are done.

1. The Basis of Time – Human Respiration

Surya Siddhanta begins with what is most close to us - our own life. And what make life possible? - respiration.

One respiration is called a 'prana' (also, Life literally in Sanskrit).

60 respirations = 1 nadi.

60 nadis = 1 sidereal day and night = 3600 respirations

So that is the definition of 1 day of man.

30 such days of man = 1 month of man.

12 such months = 1 year of man = 360 days of man.

This is one solar year (a year of man).

This is also called a day of gods.

Why do we need this? Because this is the unit of calculation of time span when it comes to large time spans like the Yugas. If we calculate in Human terms, the numbers become mind-boggling (as what you will see below).

2. Duration of a Caturyuga / Mahayuga (Four Yugas)

Now let us get into calculating the time span of the four yugas.

360 such days of gods = 1 year of gods = 129,600 days of man or 360 years of man.

(1 divine year)

12,000 such years of gods = 1 Caturyuga (also called Mahayuga)

Which is also equal to 4,320,000 years of man.

This Mahayuga is then divided into 4 yugas – Krita (4 parts), Treta (3 parts), Dwapar (2 parts), and Kali (1 part).

What does this ‘part’ mean? It means that in all there are 10 parts (4+3+2+1) and they are occupied by these four yugas. It also means that the Yuga Dharma reduces by a quarter every time a yuga changes – but that is a separate topic in itself – maybe for the next post.

So this one-tenth (1/10th) part of the Mahayuga – which is equal to 432,000 human years – is called a Charana. Thus, there are 10 such Charanas in a Mahayuga and they are divided as below:


years of man

years of gods

Charanas

Krita yuga (4 parts)

1,728,000

4,800

4

Treta yuga (3 parts)

1,296,000

3,600

3

Dwapar yuga (2 parts)

864,000

2,400

2

Kali Yuga (1 part)

432,000

1,200

1


4,320,000

12,000

10


This is one Mahayuga (Caturyuga), and is thus made of 4.32 million years of man. That’s one hell of a time span!

Each yuga is an age with specific characteristics, but more about that later, after we finish with our discussion about ‘Time’.

The Story of Banasur

Vanasur (Banasur) - The Eldest Son of Bali
----------------------------------------------------------

In the last December, we were on a road trip in Kumaon, Uttarakhand. After spending 2 days in the regions around Saat taal, Mukteshwar etc., we decided to move further up towards Champawat region and go to a less-known hill station called Abbot Mount, near Lohaghat.

This ancient region has historical and mythological importance. Champawat, once the capital of the rulers of the Chand dynasty, is famous for its natural beauty and well known temples. It is also believed that it was in Champawat that Lord Vishnu appeared as 'Kurma avtar', His incarnation as a tortoise. The River Lohawati originates near this place. Lohagarh and the nearby Tanakpur are huge marketplaces, especially of woolen clothes today.

While we were traveling from Bhowali, having crossed many mountain trails and having seen the Himalayan mountain ranges filled to our heart's desire, we came to a place called Ka…

46 Samanta-panchaka

Recently, I was studying about the Third War of Panipat (1761) for some reason, in which the Maratha forces led by Sadashiv Bhau - Balaji Bajirao 'Nanasahab' Peshwa's cousin brother - and the Rohilla Afghan forces of Ahmed Shah Abdali fought a decisive battle to the worse of Marathas. This battle is considered to be one of the largest fought in the 18th century, and also perhaps had the largest number of casualties in a single (half) day of the battle - leading to a loss of almost 100,000 human lives.

Personally, the battle has a lot of historical interest to me, as the course of Maratha history as well as the history of my country took a different turn on that fateful day. Among various reasons that historians attribute to the loss of Maratha side in this war - a much smaller force compared to the enemy and yet not following the Guerrilla tactics but meeting the enemy head-on, slow-moving camps carrying not only soldiers but also civilians, lack of a proper strategy thro…

36: Upamanyu

Note: This is not written by me, but my father. He wrote this wonderful story in a mail to me. So here's to you, Baba.

Why I am curious about Upamanyu? Coz our 'Gotra' is Upamanyu.

Who was Upamanyu? What was his significance?

We have to reach Tamil Nadu - Chidambaram.

The story begins in the lush green thick jungle of Thillaivanam, the place where there is 'Swayambhu' Linga. Whoever has a 'darshan' of this Linga, gets everything he desires. (Rightful & more on the spiritual side).

This is the very place (and the nearby area) where Lord Nataraja arrived and gave two extra-ordinary gifts to the mankind - Music & Dance.

A great sage named Madyanthinar, related to sage Vashishta, had a brilliant son, named Madyanthinar Jr. These sages were living in a small town (probably a part of Chidambaram) and away fro…
