From the chapter PART III Diary of the book “Guru Ramana – Memories and Notes” by S. S. Cohen.
8-30 a.m. Devotional songs are heard from Trichy on the radio by the Maharshi’s side. He reads a Tamil paper, apparently unconcerned. But those who know him guess that his whole attention is centred on the music, till he dozes off to the tune of the flute and the tabla.
I understand he hardly sleeps in the night. Every now and then he eludes the attendants and goes out alone. Hence three of them nowadays keep a constant watch in the night lest he should go out by himself and fall without anyone nearby to help him.
