yab-yum

In Tibeten Buddhism, or Vajrayana Buddhism, this is the symbol of the male and female sexual union--usually a union of a god or a bodhisattva and his consort--which represents the completeness of the cosmos. The male represents action, usually that of compassion, in this finite world, and the female represents wisdom, the unity of the Infinite. The male is seen as passive and the female as active.
