Please Accept My Humble Obeisances.
All Glories to Srila Prabhupada, Sri Gurudev & Gauranga.
Lord Krishna has said in Bhagavad Gita Chapter 4 Verse 8:
vinasaya ca duskrtam
sambhavami yuge yuge
"In order to deliver the pious and to annihilate the miscreants, as well as to reestablish the principles of religion, I advent Myself millennium after millennium."
In His Ramachandra avatar, He killed Ravana and re-established dharma and became an example of the Perfect Person.
In His Maha-Krishna avatar, He came to kill Kamsa.
At the end of this Kali Yuga, who is Lord Kalki coming to kill?
Please forgive me if I have committed an offense in asking this question.
Gauranga Hari Bol!
