[Jagannath] Srimad Bhagawatam 1. 4. 14

[Guest guest]

There is a chronological order of the four millenniums, namely Satya,

Dvapara, Treta and Kali. But sometimes there is overlapping. During the

regime of Vaivasvata Manu, there was an overlapping of the twenty-eighth

round of the four millenniums, and the third millennium appeared prior to

the second. In that particular millennium, Lord Sri Krsna also descends, and

because of this there was some particular alteration.

 

============ REF. SB 1.4.14

 

Can anyone elaborate on why, bcause of Krsna's advent, this overlapping took

place?
