In tantric mode of worship emphasis is laid on the supremacy of the female principle. There is also a confirmation of older cults of the mother goddess. According to hindu tantras, the female principle is the manifestation of cosmic energy which activates all matters. The male is a passive agent which can be energized only by the female. Buddhist also believe that the universe consists of an active and a passive agent. The union of which achieves absolute oneness and inactivity however they assign the active role to the male and symbol called wisdom. In both the systems of tantras the metaphysical notion of merging the principles as a means or stabilizing the universe is conceptualized as a divine couple erotically united. The tantric deities of the both religion either hindus or Buddhist are fierce and pacific manifestations, they are multi faced and multilimbed that is the reason why, we can see many gods and goddess in the temples of Nepal in their struts with multiorgan manifestations. They are also considered the deities depicted to wardoff the evil spirits and malevolent deities and to protect the good.
