Srutakirti: In the evening Srila Prabhupada would walk around chanting and would pull down a counter bead as he completed each round. It was wonderful to see. Prabhupada said to me, “When I was a householder, I would chant four rounds in the morning and four rounds before each meal. In this way I would chant sixteen rounds daily. This is effective because if you don’t chant your four rounds then you don’t eat.” He practiced this as a householder and said that we could also do it.
