Many moons ago, my dad taught yoga as a hobby. One of my early memories as a 11 or 12 year old kid, was when I attended a class of his. The class would end with a "shavasana" (corpse posture), where you'd lie down and the instructor would slowly get you to relax. I still remember my dad's voice as he asked you to imagine you're in an empty field, with a clear sky, nothing at all. Then imagine the "cosmic energy" entering your body through your head. Imagine the energy making its way down, slowly through the length of your body as it clears your thoughts and relaxes your muscles - first your face, then your neck, your shoulders, arms, and so on. As an observer, I'd notice that more than 90% of the class would be in a deep sleep before the end. And it was a big class with some 100-150 people in it. Just interesting that this "military" technique is so similar (and familiar to me)!
