So avatāra, incarnation, comes to glorify the eternal existence of the Supreme Lord. So any avatāra, any incarnation, he comes to glorify that "There is spiritual kingdom, there is God, and I have come to reclaim you to back to Godhead, back to home." This is the symptom. So therefore, by that symptom, we accept Lord Jesus Christ as śaktyāveśa avatāra, or Hazrat Muhammad, he's also. Because these two religious leaders of the world, they preached about the glorification of the Supreme Lord. And they sacrificed everything for preaching the glories of the Lord. Therefore... And their influence and their followers, there are... These are the symptoms by which we can understand that Jesus Christ and Hazrat Muhammad was, were śaktyāveśa avatāras.
So far Buddha is concerned, he's also considered śaktyāveśa avatāra. He preached this nirvāṇa philosophy. Although he did not speak about God, because it is considered that he was himself God, but the people amongst whom he preached, they were mostly atheistic people; therefore he did not preach about God. But he did not deny also. He simply wanted to make extinction of this present worldly activities. That was, yes... Nirvāṇa. And he represented the sacrifice of renouncement. He..., you may remember that the Supreme Personality of Godhead, out of His six opulences, one opulence is renouncement. So Lord Buddha's life is renouncement. He was prince. He, he was in a very young time. He renounced the world and underwent severe penances. These are the symptoms by which we can understand that he's also śaktyāveśa avatāra.
