SHOONYA- If you remain in a meditative state in Shoonya, it’s not more than 5, 6 minutes or 7 minutes at the most, not more than that. Nobody can stay there that far.
I feel most of the people, 99% of the people, experience Shoonya for a few seconds, nothing more than that. That itself will make a phenomenal change in the physiological process. We have seen any number of people undoing their chronic ailments, which is just one manifestation. ~ Sadhguru
