I occasionally do a piece inspired by my explorations into the world of meditation and the spirituality of the East. I meditate regularly using the techniques of the Thai Dhammakaya Temple of the Theravada school of Buddhism. I’m not a religious guy, but refining & exercising one’s mind is certainly worth doing if jogging is. A clearer head, the ability to more easily direct your mind’s eye (from the negative to the positive, say), serenity, and increased focus & discipline are just a few of the side effects of meditation that I’ve personally noticed.
