Yoni (; sometimes also ), sometimes referred to as "pindika", is an aniconic representation of the goddess Shakti in Hinduism. It is usually shown with "linga" – its masculine counterpart. Together, they symbolize the merging of microcosmos and macrocosmos, the divine eternal process of creation and regeneration, and the union of the feminine and the masculine that recreates all of existence. The "yoni" is conceptualized as nature's gateway of all births, particularly in the esoteric Kaula and Tantra practices, as well as the Shaktism and Shaivism traditions of Hinduism.
