is incarnated as Adwaita. This Adwaita Acharya is the incarnation of that Maha Vishnu, Who creates this material world through the agency of the material energy. Therefore Adwaita Acharya is also the Lord, or an expansion of the Lord. Why is He called Adwaita?  Adwaita  means nondual. His name is such because He is non-different from the Supreme Lord. And He is called Acharya, teacher, because He disseminated Krishna Consciousness. In this He is just like Chaitanya Mahaprabhu—although He is Sri Krishna Himself, He appeared as a devotee to teach how to love Krishna. So Adwaita Acharya appeared just to distribute the knowledge of Krishna Consciousness. He is also the incarnation of a devotee.
Krishna is manifested in five different expansions, and Himself and all of His other Associates appear as devotees of the Supreme Lord.

So Chaitanya Mahaprabhu is the Source of energy for all devotees. If we take shelter of Chaitanya Mahaprabhu for Krishna Consciousness, it becomes very easy.

In the midst of this misunderstanding, Nityananda Prabhu advised him in a dream to leave his home and go to Vrindaban. Although he was very old, he started out that very night, and came to live at Vrindaban. He met some of the Goswamis there. His tomb remains in the temple where I live in Vrindaban. This is Krishna Das Kaviraj Goswami, the author of  Chaitanya Charitamrita . This  Chaitanya Charitamrita  was requested by the devotees of Vrindaban. He began at a very old age, but by the grace of Lord Chaitanya he finished this nice, most authoritative book on Chaitanya's philosophy and life:  The Character and Activities of the Eternal Living Force .
Because he lived in Vrindaban, there are three temples that are very im-
