One of the most famous incarnations of Durga is the goddess Kali. As I discuss in this answer, she was created by Durga's incarnation Ambika in order to defeat the demons Chanda and Munda, which is why she's also known as Chamundeshwari. In any case, it is well-known that people do a variety of bizarre rituals to worship Kali, most notably non-Vedic animal sacrifice. (The Vedas prescribe animal sacrifice only in the case of Yagnas as I discuss here, not when worshipping goddesses like Kali.)
But my question is about the worship of a goddess closely related to Kali, named Tara. In this excerpt from the Narada Purana, various rituals to worship the goddess Tara are described, including this one:
In the cremation ground or in a vacant house, or in a temple, or in a lonely place, in a mountain, in a forest, the knower of the mantra shall climb onto a dead body that has been killed in the battle-field or on a child of six months, should make an effort for the propitiation of the vidya (of Tarini), thus he would soon be able to make it fruitful.
I can understand sitting on a dead body and chanting mantras. (Well, I can't really understand that either, but I can at least picture someone doing it.) But my question is, what does it mean to say that the devotee of Tara "shall climb ... on a child of six months"? Does that mean sitting on a live six-month old baby, or a dead body of a six-month old baby? Do any devotees of Tara do this practice today?
I should add the Narada Purana is considered to have a lot of interpolations, so this may not be a genuine passage.
