dakini during one's yogic love practice, then this energy
is leaked away. It is not good to talk; the whole
vajra-love process should be carried out in silence.
Downward-moving energy: This concerns the
vajra-love action of penetration and withdrawal. The
rhythm should be slow and the penetration sometimes
deep and sometimes shallow, not always quick and deep
like that of the common lustful person. If one practices
only quick and deep action, then this is a leak of the
downward-moving energy.
Energy of the navel: This energy abides in the lower
half of the body. If one frequently changes the posture
for vajra-love—and there are many different positions
for its practice—then this energy is leaked away.
All-pervading energy of the body: in yogic love-practice,
there are four events: The descent of the pleasure,
retaining the semen, taking up the semen, and making
the semen pervade everywhere in the body. If one
practices too long and repeats some of these steps again
and again, then a leak will occur of this all-pervading
energy. One should only meditate on sunyata during the
whole process, and there is no need to repeat its parts.
"These four leaks of energy-speech are my own
opinion," said the yogi, "and although there is no
basis for them in the works of the ancients, still they
are quite reasonable."
