I worship the Supreme Personality of Godhead, Govinda, who is the original personnondual, infallible, and without beginning. Although He expands into unlimited forms, He is still the original, and although He is the oldest person, He always appears as a fresh youth. Such eternal, blissful and all-knowing forms of the Lord cannot be understood by the academic wisdom of the Vedas, but they are always manifest to pure, unalloyed devotees. (Brahma-samhita 5.33) The Brahma-samhita describes the avataras. Indeed, all the avataras are described in the authentic scriptures. No one can become an avatara, or incarnation, although this has become fashionable in the age of Kali. The avataras are described in the authentic scriptures (sastras), and therefore before one risks accepting a pretender as an avatara, one should refer to the sastras. The sastras say everywhere that Krsna is the original Personality of Godhead and that He has innumerable avataras, or incarnations. Elsewhere in the Brahma-samhita it is said, ramadi-murtisu kala-niyamena tisthan: [Bs. 5.39] Rama, Nrsimha, Varaha and many others are consecutive expansions of the Supreme Personality of Godhead. After Krsna comes Balarama, after Balarama is Sankarsana, then Aniruddha, Pradyumna, Narayana and then the purusa-avatarasMaha-Visnu, Garbhodakasayi Visnu and Ksirodakasayi Visnu. All of them are avataras.
