Prabhupāda: So when there are discrepancies of this violation of law, there is incarnation of God. So Lord Buddha appeared in that way. Yes.
Tamāla Kṛṣṇa: "Therefore each and every avatāra, or incarnation of the Lord, has a particular mission, and they are all described in the revealed scriptures. Nobody can be accepted as an avatāra without references to the scriptural indication. It is not a fact that the Lord appears only on Indian soil. He can advent Himself anywhere and everywhere and whenever He desires to appear. In each and every incarnation He speaks as much about religion as can be understood by the particular people under their particular circumstances, but the mission is the same: to lead people to God consciousness and obedience to the principles of religion. Sometimes He descends personally, and sometimes He sends His bona fide representative in the form of His son or servant."
Prabhupāda: So there are some protagonists. They say that God cannot come personally. Why? Why God should be restricted? Is God under your regulation or restriction? Then what kind of God He is? Yes. God can come personally out of His compassion. That is possible. Yes. And He comes. He says here in this verse that "I come." But it is not that somebody will imitate and he will say that "I am God." No. That also not. You have to test actually. That test, if you have got, if you are conversant with the principles of God appearance, disappearance, incarnation, then you can understand who is a pretender and who is actually representative of God, by action.
