The myth that Hayagriva and Śrīla Prabhupāda worked extensively, side by side, on Bhagavad-gita As It Is

 “While it is not generally known, for two years Śrīla Prabhupāda sat with Hayagriva and patiently transformed His intimate realizations into a level of refined expression onto which He then comfortably placed His name. The resulting literary expression was the wondrous 1972 Bhagavad-Gita As It Is.

Responding to this assertion, Brahmananda Prabhu, the president of Śrīla Prabhupāda’s first temple in America, said, “It’s out of the question.” The dates of letters in the Folio VedaBase show that during the period when Bhagavad-gita As It Is was being edited the total time Hayagriva and Śrīla Prabhupāda were even together in the same city, what to speak of sitting together working, was, at the most, less than five months. And, again according to Brahmananda Prabhu (and confirmed by Umapati Maharaja, another of the earliest devotees), Hayagriva mainly worked on his own.
