Kalachakra: Bodhichitta

With the pride of vajra holder,
the vajra with lotus enters the lotus.
With lingam placed into the bhaga,
the yogi performs hum phat;
the bodhichitta [sexual energy] is not emitted.

One's own secret-area five-pointed vajra [male sexual organ] marked with a lotus enters the consort's lotus [female sexual organ]. Within that state the yogi holds the pride of being the vajra-holder main deity Kakalchakra, he utters the syllables hum phat, and dwells within the activity of union arising from placing the father's lingum into the mother's bhaga. This brings the elemental bodhichitta [sexual energy] down to the tip of the jewel, where it is not to be emitted.
