The Hare Krishna Tree in N.Y.
On October 9, 1966, Prabhupada and his followers sat beneath this tree and held the first outdoor chanting session outside of India. Participants chanted for two hours as they danced and played cymbals, tambourines, and other percussive instruments; the event is recognized as the founding of the Hare Krishna religion in the United States. Prabhupada's diverse group that day included Beat poet Allen Ginsberg (1926-1997). Krishna adherents continue to return to the tree to acknowledge its significance.
