1. A ‘Manavantara’ – Bringing It All Back
Again, let’s bring this back to Human understanding.
A day of Brahma has 14 Manvantaras (like 12 hours). Similarly one night has 14 Manavantaras.
Each Manavantara is made of 71 Mahayugas, plus the sandhis. Each sandhi is equal in time as one krita yuga – note, this is not one Manayuga, neither one yuga, but one krita yuga, i.e. 4 Charanas of a Mahayuga.
So let us back-calculate and check where we get to:
1 Mahayuga = 4,320,000 years
1 Manvantara = 71 Mahayuga
1 day of Brahma = 14 Manavantaras + 15 sandhis
= 14 x 71 Mahayugas + 15 x 4 Charanas
= 994 Mahayugas + 60 Charanas
Now, 60 Charanas mean 6 Mahayugas (each Charana is 1/10th of a Mahayuga). So:
1 day of Brahma = 994 Mahayugas + 6 Mahayugas = 1,000 Mahayugas.
Which is the same calculation we did earlier for 1 Kalpa (Day of Brahma).
2. So, where are we?
Now, to see where we are in this whole scheme of things:
We don’t know which Brahma it is. There were thousands before, and there will be thousands later. This is Multi-verse.
Let’s talk about the Uni-verse i.e. this current Brahma of ours. This is what the scriptures say:
“We are currently in the 28th kaliyuga of the first day of the 1st year of the shvetavaraha kalpa of the second parardha of Brahma in the reign of the 7th Manu, Manu Vaivasvata”
What do we make of it? Read it backwards.
Firstly, we are in the first day of the 51st year of our current Brahma (out of 100).
Then, We are in the 7th Manvantara of Brahma’s this day (out of 14).
And in this Manavantara, 28 Mahayugas have already passed (out of 71).
Let us consider the starting point as this day of Brahma. Why? That is because when Brahma sleeps there is no creation, no life. So any time before this Brahma was awake today is of no meaning to us.
So let us calculate how many years have passed since today started for Brahma. Remember one day of Brahma is 4.32 billion human years.
We will use Mahayugas as the unit. Remember
1 Mahayuga = 12000 divine years = 432,000 human years.
Step 1: For 6 Manvantaras (i.e. for the 7th Manu) we have 71x 6 = 426 Mahayugas
Step 2: Then we have the sandhis - gaps between each Manvantara which is 7 x 4 Charanas = 28 Charanas = 2.8 MahaYugas
Step 3: Then we have the current Mahayuga in our Manvantara, which is 28th in number. So there are 27 Mahayugas completed.
Step 4: Now coming to this epoch, we are in a Kali yuga – which is the last 1/10th of the Mahayuga. (Remember the earlier post, which divides a Mahayuga in 10 Charanas? The last Charana is a Kali yuga). So 90% of this Mahayuga is completed.
All the above put together we have:
426 + 2.8 + 27 + 0.9 = 456.7 Mahayugas
So, 456.7 have been already spent in current day of Brahma. There 543.3 more to go before we all are absorbed back into the Brahma (since total Mahayugas are 1,000 in one day of Brahma).
456.7 Mahayugas = 456.7 x 432,000 human years
= 197,294,400 human years (about 2 billion years)
So now you see, about 2 billion years have passed out of 4.32 billion years. There are 2.32 billion human years more before Brahma sleeps.
Of course, for us here and now, what is more important is when the current Epoch – this kali yuga will end. Since then all will be immersed in water.
It is explained that Kali-yuga began with the disappearance of Lord Krishna from the planet. This has been calculated to be 3102 B.C. Since Kali-yuga is described as being 432,000 earth years in length, with 5,000 years and more already passed, then the age of Kali-yuga has approximately 426,000 more years to go.
So even with this calculation -- all those doomsday soothsayers, it looks like you need to wait a while !!!
