Who is Kalki Avatar?

[Shri Anil asked: Padanamaskaram Swami, Please grace Your responses to the following question. At Your Lotus Feet-anil

Who is Kalki Avatar? Some Muslim’s believe that Holy Prophet Muhammad was the Kalki Avatar who rides on the horse with a sword. Some equate second coming of the Jesus is the Kalki Avatar. How to correlate this with Krishna’s saying in Gita that He will come in every human generation? Kindly enlighten us.]

Swami replied:- God Krishna said that He will come down to the earth whenever there is a necessity. It is better to depend on this single statement instead of comparisons created by our idle monkey brains, which are of no use. The omniscient and omnipotent God can take care of good administration to be provided to His own creation. Let us worry about the administration of our monkey minds, which is very essential to get the grace of God.
