"Here (within this body) is the Ganges and Jumna...here are Prayaga and Benares - here the sun and the moon. Here are the sacred places, here the Pithas and Upa-pithas - I have not seen a place of pilgrimage and an abode of bliss like my body."Saraha (Indian Tantric Buddhist adept)
Tantrism and Neotantrism by Georg Feuerstein, Ph.D. - the best, most accurate article I have ever read on Tantra, Tantric sex, and what passes for Tantra in the modern West (what Feuerstein terms "Neotantrism"). If you only read one thing on Tantra, I would recommend you read this!
Hindu Tantrik Home Page: (UK site) (US mirror site) - by Mike Magee - a superb, encyclopeadic site! Will definitely appeal to the dedicated student or practitioner.
