Revati and 27 CaturYugas Authorship and Copyright Notice: All Rights Reserved: Satya Sarada Kandula

Revati’s father, Raivata Kakudmin and Revati lost 27chaturyugas (108 yugas), during a visit toBrahma:

.”abhiyātaḥ — have passed; tri — three; nava — nine; catur-yuga — four yugas; vikalpitaḥ —

thus measured.http://bhagavata.org/canto9/chapter3.html

‘for many successions of ages have passed away whilst you were listening to our songsters: now 

upon earth the twenty-eighth great age of the present Manu is nearly finished, and the Kali 

 period  is at hand. http://www.sacred-texts.com/hi n/vp /vp093.htm

How traditionalists explain this:

1. To explain this, we can go into the Time-Dilation story told in the Bhagavatam. About how

Revati’s father and Revati lost 27 chaturyugas (108yugas), during a visit to Brahma,

because Brahma is on a different time-scale.

2. Or we can go into another puranic theory which says that each of these stories took place

in different kalpas, or different manvantaras. According to this the main events of the

stories take place in every kalpa and there are finite variations in any specific kalpa. That

way everyone gets to be right in some parallel universe or some time cycle.

I propose that an astronomical story has been overlaid with a legend. It is my thinking that

Revati, here refers to the star and not to the woman.

Revati is the name of the star   99hPsc, which is the brightest star of Meena Raashi . There are 27 stars, in

the Hindu zodiac. The story is one of Revati ‘returning’ to a place after 27 units of time, 27 Mahayugas or 

Chaturyugas. It demonstrates a knowledge of the precession of equinoxes.

Some background and calculations:

5. 360 degrees = 360*60 minutes = 360*60*60 seconds of arc = 1296000 seconds of arc

6. 1296000secondsofarc/50.26secondsofarc/year=25785.91years

8. If the technology of measurement at that time gave a figure of 48 seconds of arc per 

year for the westward recession of Aries, then it would take 1296000/48 = 27000 

years for Revati to return. 27000 years is the figure you normally find in many articles.(This would mean a 4.5% relative error in measurement in seconds of arc. Which is very 

small ).

9. If 27000 years give us 27 caturyugas, and if the ratio of the individual Yuga lengths in each

caturyuga is 4:3:2:1 with the Kaliyuga being a 100 years long, then Each caturyuga is 1000

years long.
