Master & Swamiji slept very little.

Just a few hours a night. Master would come out of his Kutir promptly at 0400. Swami Vishnu had to be there to walk with Him. After an Assassination attempt, ( a man with an axe) Swamiji and another slept down by His door to ensure nothing happened. Swami Sahajananda said, “ I think Gurudev would snore”, He said,” A lot of saints did.”

Who knows.
