I recently saw a site that uses the hand forms/position during Standing meditation! I knew of them sitting. In my quest for a unified energy system , A Big Question: Which mudras correspond to which channel ? This will provide me with a shortcut instead of trying to get specific postures. The idea is to combine Horse Stance with sound vibration, with correct Mudra,with color visualation, correct "facing orientation", Buddhist then Reverse Taoist breathing and likewise from seated Zazen using it. Any help? I posted for example in "Check it out" of a research source if you manually input the Full address.
