I was with several devotees in Srila Prabhupada's room at our small temple in Edinburgh, Scotland. As he was sitting, a shaft of sunlight entered the window and lit up the whole room. Srila Prabhupada remarked with a wave of his hand, "When you become Krsna conscious, it is just like that."
Svati D.D., from a 1978 BTG
