Universe according to Mahabharat
This is according to Mahabharat. Please don't flame me for it.
The Life of the entire Universe is 100 Brahma Years which is the
production (not creation; Hinduism does not believe in creation,
because creation implies absence of material) of one most evolved
jiva, called Brahma, Hiranyagarbha or Purushottam, of the previous
cycle. This jiva projects the universe by His own Will through
meditation. To distribute the results of karmas, this Being
meditates to know all about jivas and their karmas that lie in
a dormant state (avyakta) during Pralya. At the end of 100 Brahma
years, this jiva joins Parabrahma and another most evolved jiva
is picked for another cycle. This is going on without a beginning
and it has no end.
A Brahma Day (one kalpa) is one cycle, ie., it includes the
periods of Sristhi (Dawn), Sthiti (Manifestation) and Pralya
There is one partial dissolution every 1000 yugas called Nimaitya
Pralya (I don't know how much universe is destroyed. Any idea?).
There is Absolute (I mean Absolute) dissolution after 100 Brahma
Years. The univese starts from scratch.
1 yuga = 4.32 million years
One Brahma Day = one kalpa = 1000 yugas
1 Brahma Month = 30 Brahma Days
12 Brahma Months = one Brahma Year
Life of the Brahma = 100 Years
The age of the current Brahma is 50 years. The current Kalpa in the
51st year is srisvetavarahakalpa.
According to Mahabharat, the kal yuga started on the midnight
of 17th and 18th February, 3102 BC.
