Book excerpt: Though often associated with sexual practices, traditional Hindu Tantra presents a body of sophisticated psycho-physical techniques for attaining enlightenment. The tradition is often perplexing to the uninitiated due to Tantra's use of metaphors that serve to keep the teachings secret from outsiders. The author reveals the secrets and hidden meanings of important Tantric symbols and distills 50 years of practice and teaching into a form accessible to readers new to the tradition. Drawing on his own experience, the author presents a demystified and simplified version of Tantric practices that any sincere spiritual aspirant East or West can actually do.
