Driti Utsa has some on beta and endowed with enthusiasm and patience. A satvik mind is fresh, I have seen such people,. old monks, but such fresh minds, child like fresh minds. They're looking at everything with the eyes of a child. So that is freshness is there, enthusiasm is there and yet systematic, disciplined, sana is sana is slowly, slowly, systematically. The whole iceberg is prana, the physiological process is keeping this body alive. Then go to something more subtle which is the mind, thoughts, ideas, memories, emotions, desires. Beyond that you push further, you will reach a very subtle blankness.
