Certainly, when I learned Transcendental Meditation back in 1989 it was a life-changing experience, though I gradually moved away from the more cultish aspects of TM. Perhaps anyway, as the Dalai Lama put it, "sleep is the best meditation".
I learned Transcendental Meditation (TM) through a formal course in 1989. I don't entirely buy the claim that just a few minutes' daily meditation can make a difference between an anxious existence and a life of quiet contentment...but it helped. TM opened inner portals that, happily, have never closed.
"A wise lady once told me that when you find your ideal job, you will do it for less than they pay you and when you find your calling you will do it for free. This is my ideal job. I hope you find yours." - Martin Tichenor, Volunteer Director for a medium security prison in Missouri
Finding and fulfiling what you consider to be your purpose must rank among the greatest of all assets.
