31.8.10

"At that time, I still had conscious awareness and was cognizant of external occurrences. Then the thought occurred to me again: 'Now I can enter the breathless dhyāna.' Then I entered the breathless dhyāna and counted the in-breaths and out-breaths. Having counted the in-breaths and out-breaths, I felt air coming out of my ears, and the sound of the wind at that time was like the roar of thunder. Then the thought occurred to me again: 'Now I will shut my mouth and stop my ears, so that breath does not exit.' When the breath did not exit, the internal air came out through my hands and feet. Because the breath could not exit through my ears, nose, or mouth, the internal sound at that time was like the roar of thunder; I was like that at that time. At that time, my consciousness still followed the movements of my body.
