What is Tantra?
In this video Dr. Robert Svoboda talks about what Tantra is and isn’t, and what he learned about this transformational, non-sectarian way of experiencing Reality from his mentor, the Aghori Vimalananda.
You can take a course with Dr. Svoboda on the subject of Tantra & the Five Elements (which has much better audio quality than this video).
