I would advise you to undergo atleast once the "Inner Engineering" program by Isha Foundation. It has nothing to do with any religion, caste, region. People from all over the world are getting benefitted from it and transformed their lives. Jaggi Vasudev better known as Sadhguru is the yogi, mystic and humanitarian who founded Isha Foundation, a non-profit organization run by the volunteers.
