One of the most powerful manifestations of the energy of Mahakala, the form of the deity seems to emerge from Mahakala’s head. She is the source of all energies, kinetic or otherwise. She is the sustaining power which two figures feeding on her breasts symbolise. Her prominently defined ‘yoni’ – vulva, which three snakes guard and two human figures feed on, is both, the source of kindling Kundalini as well as of fertility. In Tantra-sadhana ‘yoni’ has rare significance, as ‘yoni-sadhana’ not only kindles dormant energies but also leads to ‘Sahasrara-chakra’ – the thousand petal-lotus plane.
