To take another example, the ninth precept states: "You
should not doubt the purified Dharma." Purification in
the Hinayana and sublimation in the Mahayana has long
passed, so what does that precept mean? The sorrow of
lust has been purified by the Lesser Vehicle practices,
where the opposite sex is thought of as very dangerous
and one's own physical body is analyzed to see the
nature of the thirty-six corrupt parts (see Ch. IX, E, 1, a,
i). Following this comes the attainment of a meditative
body and its subsequent sublimation in sunyata, so it is
no longer a flesh body. Further, the physical body
(realized as sunyata in the Mahayana), becomes
transmuted in the Tantra of the growing yoga (see Ch.
XIII, Part One, D), when one attains a Buddha-body.
This body, purified and with an opened median channel,
is the body used in vajra-love. In this initiation even the
name "penis" is not given to the reproductive organ; it is
called a "vajra." The practices of yoga, therefore, do not
resemble human love, one other important difference
being that in Tantra the semen is retained.
Mr. Chen then recapitulated:
From the Hinayana meditations, we come to the
Mahayana, when the human organ becomes sunyata.
From sunyata meditations, one passes on to the five
wisdoms and the five elements, forming the vajra. This
vajra, which is not at all like the ordinary human organ,
