the "head" of the connection between the third and the
fourth forms.
The fourth form—vajra-body—should accumulate all
the merits of the three kayas of Buddhahood, but the
three secrets of body, speech, and mind cannot be
symbolized; they must be formed. Hence,
personification is needed, and that is the end of the
connection between the third and the fourth forms.
When the vajra's extension has been drawn back to the
size of the meditator's human body, that embodies it
into a personified vajra-body. The upper part of the
vajra becomes the hair-tuft, and the lower part of the
vajra becomes the upper part of the male organ. The
trunk of the vajra becomes the median channel, the main
source of all parts of the Buddha-body: the brain,
nervous system, and all the organs. All these systems
and organs appear outwardly like those of a human
body, but inwardly they are full of the compassion and
wisdom of Buddhahood, so they are quite different from
those of an ordinary human body, which contains evil
karmas.
Some of the rituals call for personification of Vairocana,

latter for the practice of saving others, for the position
of a bodhisattva is closer to the sentient beings than that
of a Buddha. The yoga dealt with in this appendix
