Chinese Dragons are legendary creatures in Chinese mythology and folklore, with mythic counterparts among Japanese, Korean,Vietnamese, Bhutanese, Western and Turkic dragons. In Chinese art, dragons are typically portrayed as long, scaled, serpentine creatures with four legs. In yin and yang terminology, a dragon is yang and complements a yin fenghuang ("Chinese phoenix").
Heruka is a principal Deity (Tantric Buddha) of Mother Tantra, who is the embodiment of indivisible bliss and emptiness.Heruka has a blue-coloured body, four faces, and twelve arms, and embraces his consort Vajravarahi. These two are not two different entities, as an ordinary husband and wife are two different people; in reality, their divine embrace symbolizes the union of great bliss and emptiness, which are one and the same essence.
