Many people know about The Cycle of 4 Yugas and DashaAvatars of Shriman Narayana ,but very few know that the Dashaavatars are not bound to the cycle of 4 Yugas. The Avatars of Bhagwan are infinite in number and he incarnates randomly, so technically Dashaavatars are distributed over the entire Kalpa, starting from Varaha avatar before the beginning of Shweta Varaha Kalpa(current Kalpa).
This will help those who want to understand Hindu time distribution.
My question is related to the future avatar Kalki Avatar. Since there were many Kaliyugas prior to this Kaliyuga, then why didn't Bhagawan appear in previous Manvantara Kaliyuga? Is this Kaliyuga the most polluted?
