10. This is because when mind is subtle, breath is subtle; when mind is
unified, it moves energy. When breath is subtle, mind is subtle; when
energy is unified, it moves mind. Stabilization of mind must be preceded by
development of energy because the mind has no place to set to work on; so
focus on energy is used as a starting point. This is what is called the
preservation of pure energy.
11. You don't understand the meaning of the word movement. Movement is
pulling the strings; the word movement is another word for control. Since
you can cause movement by vigorous action, how could you not be able to
cause stillness by pure quietude?
12. The great sages saw the interrelation of mind and energy and skillfully
set up an expedient for the benefit of people of later times. An alchemical
text says, “The hen embraces the egg, always mentally listening." These are
the finest instructions. The way a hen can give life to an egg is through
warm energy; warm energy can only warm the shell and cannot penetrate
the inside, so she mentally conducts the energy inward. That "listening" is
single-minded concentration. When the mind enters, the energy enters; with
warm energy, the birth takes place.
13. Therefore even though the mother hen goes out from time to time, she is
always listening, and the concentration of her spirit is never interrupted.
Since the concentration of the spirit is never interrupted, then the warm
energy is also uninterrupted day and night, so the spirit comes alive.
