"Tantra begins with experience of emptiness-the pregnant space from which form arises. Form is simply that which arises-and does not need to be viewed in terms of pure or impure. Human bodies are as they are and are available for appreciation. Samsara is not a separate existence to nirvana. They are the same experience-it is view that changes."
