There are traditionally three ways to realise the nature of passion in the yogic tradition of Tantra. First in creation-phase practice one can visualise the yidams as yab-yum in sexual union... Second one can practice tummo (caṇḍalī) or the generation of internal heat through the subtle body practices of the vital breath moving into the central channel. Third, one can practice so-called sexual yoga (karmamudra, lekyi chagya) with a consort. Realising the true nature of passion in all of these forms transforms ordinary passion into the basis for the experience of great bliss (mahasukha), which greatly accelerates the removal of emotional and mental obscurations in one's practice.
