“Liberation is achieved through enjoyment. Happiness is gained through enjoyment. Therefore, by every effort, a Sadhaka should become an enjoyer. The wise man should always avoid blame, disgust or shame of the yoni. Unless the yoni is worshipped using the Kulachara method, even one hundred thousand Sadhanas are useless.” -Yoni Tantra
In Tantra, the Yoni is revered as the feminine portal creation. A Yoni Puja is a ritual to honor and worship Shakti, the divine mother and divine feminine principle. It is considered the most powerful form of worship and devotion.
Whether a symbol, sculpture or painting of a Yoni, or the Yoni in living form, the focus of a Yoni puja is in the veneration and reverence of the cosmic feminine act of creation. The Yoni is the source of all things manifest.
Not all devotees are fit to practice Yoni Puja. While extremely powerful, it requires a certain level of cultivation of the devotee, in which he has overcome his beastly or animalistic drive (pashu bhava) - “Never worship the yoni in front of pashus. Using the yoni sādhana method, one definitely becomes like Vishnu, of this there is no doubt. Whosoever does this is praised by the Suras and Asuras in heaven and the underworld. Only one acting with Vira Sadhana is liberated from sorrow.”
