Stuff Bob thinks is cool number 4
In July 2014 I learned Vedic meditation, a very similar technique to transcendental meditation, popularized in the west largely by the Beatles with Maharishi Mahesh Yogi and, more recently, the David Lynch Foundation. I've found it to be incredibly rewarding and interesting while also reducing stress and inspiring creativity. There are countless books, podcasts, literature, etc on the technique. If you're interested I'd recommend checking out Benturshenmeditation.com based out of NY and Jeff-kober.com based out of LA. Jeff also has great recordings on his website of group meditations he runs as well as "thoughts of the day" you can subscribe to.
