Frank started writing me after reading my books. He's a person that appreciates specific answers to his specific questions. This is an edited reconstitution of our correspondence and is meant as a reference.
[Here is my crude drawing of the backward-flowing method, that is, the sensations felt in the lower belly once you become able to perceive them. Notice in Figure 1 the breath-energy is circulating down the back and up the front. After you command it to change, the breath-energy begins to circulate in the opposite direction (Figure 2).]
Again I'm a poor artist, but the drawing seems to help. Alex Grey, where are you when we need you?
