When Srila Prabhupada was having difficulties with Paul Murray (David, in Satsvarupa Das Goswami’s ‘Srila Prabhupada Lilamrita’) at the Bowery loft, he came to me for help. I didn’t fully understand what the problem was, so Srila Prabhupada said: “We have a saying. Guru-mara-vidya. You sit opposite a guru, learn from him everything, then you kill him, move his dead body aside, and sit in his place, then you become the guru.”
