This is the ultimate truth of Qi cultivation, and also the ultimate truth of martial arts.
"Let your Qi sink deep, your strength solid as the mountain roots."
"When guiding Qi, let it return to self-flow, no mind to where outside force comes from."
"Distinguish between reality and illusion clearly; in each place determine what's real and what isn't, carry this distinction everywhere. Qi must be surging, spirit should be internalized, ensure no flaws, no uneven parts, no interruptions."
"Use intent not force. Move with others, fold when they bend, where you contact, your mind must be there."
"No fixed direction, strike after the opponent yet control before the opponent."
"My strength meets theirs, finding the straight in the curve, using their force against them, the technique of Four Ounces Move a Thousand Pounds."
Baji, Bagua, Xingyi, Tai Chi!
Within lies the supreme principles of boxing.
