Question : As I know, Lord Krishna appears in this material world with His original form (human-like form) in Kali-yuga. My question is why the Lord chooses to reveal Himself in His original form especially in this yuga?
Answer by Romapada Swami :
The incarnations of the Lord appear in a scheduled manner in each of the four yugas, throughout the course of the history of the universe. As Krishna explains in Bhagavad-gita, He descends millennium after millennium to reestablish religious principles, and so on. Why a particular incarnation appears at a particular time is difficult to explain; He does so according to His own sweet will. The Lord appears in order to fulfill some mission, but above that, He appears for His own pleasure, according to His Supreme Will. Prahlada Maharaja explains this in his prayer to Lord Nrsingadev: “One may consider that the Lord appeared in that fearful form to protect His devotee Prahlad, or to keep the boons of Brahma intact, but factually it is for Your own pleasure that You have performed this pastime.” So we understand that Krishna’s appearance in His original form before the beginning of Kali-yuga, or more precisely at the end of Dvapara yuga once in a day of Brahma, as being according to His own sweet will.
