A. C. Bhaktivedanta Swami Prabhupada
He was initiated by ISKCON's founder A. C. Bhaktivedanta Swami Prabhupada and received name Ranchora Dasa, which means "servant of Krishna". Ranchor means, in Krishna's case, "a person not willing to fight on this one occasion." On one celebrated occasion, Krishna did not want to fight and left the battlefield without fighting, so he's called Ranchor.
