Bless and sit down. Forgive and forget. Practice kindness all day to everybody and you will realize you're already in heaven now. That's the story. That's the message. Nobody understands it, nobody listens, they're all running around like chickens with heads cut off. I will try to teach it but it will be in vain, it's why I'll end up in a shack praying and being cool and singing by my woodstove making pancakes.
Breathing is one internal function that the conscious mind can control with comparative ease. The effect of controlled breathing is almost like communication with all conscious parts of one's being saying to them, "Simmer down and listen; there is something beyond the turmoil". It is communication in action that often works when words merely go in one ear and out the other, not even changing the cognitive mind. In essence, the effect is to turn all the elements of our will toward stillness and waiting.
