Romapada Swami : Prabhupada rang the bell on his desk, and his servant came in and offered obeisances. The servant was supposed to have done something but he had neglected to do it. Prabhupada's mood shifted from one of happily appreciating the devotees' artwork to being strong and firm with his servant. Everybody in the room became silent. As soon as the servant left, Prabhupada withdrew that anger and was again as before. Anger did not control him, but he used that mood to instruct a disciple and help that disciple stay properly situated in devotional service.
