The Kāpālika tradition was a non-Puranic form of Shaivism in India. The word Kāpālikas is derived from kapāla meaning "skull", and Kāpālikas means the "skull-men". The Kāpālikas traditionally carried a skull-topped trident (khatvanga) and an empty skull as a begging bowl. Other attributes associated with Kāpālikas were that they smeared their body with ashes from the cremation ground, revered the fierce Bhairava form of Shiva, engaged in rituals with blood, meat, alcohol, and sexual fluids.
According to David Lorenzen, there is a paucity of primary sources on Kapalikas, and historical information about them is available from fictional works and other traditions who disparage them. Various Indian texts claim that the Kāpālika drank liquor freely, both for ritual and as a matter of habit. The Chinese pilgrim to India in the 7th century, Hsuan Tsang, in his memoir on what is now northwest Pakistan, wrote about Buddhists living with naked ascetics who cover themselves with ashes and wore bone wreathes on their heads, but Hsuan Tsang does not call them Kapalikas or any particular name. Scholars have interpreted these ascetics variously as Digambara Jains, Pashupatas and Kapalikas.
The Kāpālikas were more of a monastic order, states Lorenzen, and not a sect with a textual doctrine. The Kāpālika tradition gave rise to the Kulamārga, a category of tantric Shaivism which preserves some of the distinctive features of the Kāpālika tradition. Some of Kāpālika Shaiva practices are found in Vajrayana Buddhism, and scholars disagree on who influenced whom. Today the Kapalika tradition has merged with Natha order, where its practiced with the Kaula rituals.
One of the earliest references to a Kāpālika is found in Hāla's Prakrit poem, the Gāthāsaptaśati (third to fifth century A.D.) in a verse in which the poet describes a young female Kāpālikā who besmears herself with ashes from the funeral pyre of her lover. Varāhamihira (c500-575) refer more than once to the Kāpālikas thus clearly establishing their existence in the sixth century. Indeed, from this time onwards references to Kāpālika ascetics become fairly commonplace in Sanskrit ...
