The tantric tradition, from which hatha-yoga stems-out, is probably the only exception to the method of renunciation, characteristic of all forms of inner research, in the West as well as in the East. Despite the goal of yoga being the realization of a unitary dimension of reality, in which our existence as single and separate individuals is overcome by a total, non-dual and therefore joyful experience, most of the classical vedic yoga traditions entail an ascetic path of austerities and renunciation which ends up recalling a dualistic view, between what is pure and what is impure, between what is ephemeral and what is essential. Thus, the well-known distinctions of body and soul, of a sensitive dimension and a spiritual one are also to be found in the land of the East. On the contrary, Tantra, a quite late philosophical expression (VIII-X A.D.), is likely to have its roots in the practices of the ancient Indus Valley Civilization, connected to the cults of fertility and the ones of the Mother Goddess. Tan-tra literally “means of expansion” and, as such, abolishes every dualism, in the belief that every aspect of reality can represent an expansion tool, that is, a doorway to the Whole.
