Yoni (IAST: yoni; sometimes also IAST: yonī), sometimes referred to as pindika, is an abstract or aniconic representation of the Hindu goddess Shakti. 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.
