Yab-yum (Tibetan: ཡབ་ཡུམ། literally, "father-mother") is a common symbol in the Tibetan Buddhist art of India, Bhutan, Nepal, and Tibet. It represents the primordial union of wisdom and compassion, depicted as a male deity in union with his female consort through the similar ideas of interpenetration or "coalescence" (Tibetan: ཟུང་འཇུག Wylie: zung-'jug; Sanskrit: yuganaddha), using the concept of Indra's net to illustrate this.[1]
The male figure represents compassion and skillful means, while the female partner represents insight. In yab-yum the female is seated on the male's lap. There is a rare presentation of a similar figure but reversed, with the male sitting on the female's lap, called yum-yab.[2]
