Question: Is it possible to make progress while you are asleep?Sri Chinmoy: In ordinary sleep you are tired, exhausted. But if you can stay in Yogic sleep, that is not ordinary sleep. It is soundless sleep. But “soundless” is a very mild word. In that sleep, you do not have any dream, you do not have any desire, you do not have any conflict with the finite. Only you remain in the infinite. Your consciousness stays in Infinity and Eternity. So in this kind of sleep, you do make the fastest progress. It is not sleep but conscious aspiration that will help you. Just by sleeping many hours a day, if you feel that you will get realisation, then you are sadly mistaken.
