What we have to do is bring deep sleep into the waking state. ,to get ‘ conscious sleep’ — Maharishi Ramana.
Comment: This method I am doing from so many years. When we sit down closing our eyes,after some time thoughts by observation starts to drop automatically, then if thoughts comes we question to ourselves ” to whom thoughts are arising” then we say to me. then give second question ,’ who am I’ by repting over and over again, mind will emerge in the self leaving the experience of ‘ bliss’ .
