Jayadeva Gosvami, in his Gita-govinda, has sung as follows: "The Lord has saved the Vedas in His form as a fish, and He has borne the whole universe on His back in the form of a tortoise. He has picked up this earthly planet from the water in the form of a boar. He has killed Hiranyakasipu in the form of Nrsimha. He has cheated Maharaj Bali in the form of Vamana. He has annihilated all the dynasties of the ksatriyas in the form of Parasurama. He has killed all the demons in the form of Lord Rama. He has accepted the great plow in the form of Balarama. He has annihilated all the atheistic persons in the form of Kalki. And He has saved all the poor animals in the form of Lord Buddha."* These are some of the descriptions of the incarnations emanating from Krsna, and from the Srimad-Bhagavatam it is understood that innumerable incarnations are always coming out from the body of Krsna, just like waves in the ocean. No one can even count how many waves there are, and similarly no one can count how many incarnations are coming from the Lord's body.
