Tranakarta: Once in Prabhupada's room, Sri Govinda's son Sudarshan, who was 2 or 3, touched his crayon to a picture of Srila Bhaktisiddhanta. Prabhupada said, "Don't do that to my Guru Maharaj!" Sri Govinda's wife took Sudarshan out of the room and Sri Govinda felt bad that his son had done that. Prabhupada said. "When a young child is a rascal it means he will be a great soul when he grows up." Prabhupada took away Sri Govinda's anxiety.
