"Tantra often runs into trouble in the West, because it utilizes transgression as the vehicle to transcend dualism in certain cases. To even begin to understand tantra, however, we must bear in mind the cultural and philosophical context in which it exists. Tantra originated as a range of bodily technologies for perfecting the individual. Many of its practices, texts, beliefs and traditions are opposed to any normative order and serve as a form of counterculture in India. Its rejection of order takes the form even of sanctioning the deliberate violation of norms, particularly those centred on ritual purity. Over time, there occurred a healthy cross-fertilizing back and forth with Vedic and other traditions. Elements may have been borrowed from Vedic and other rituals, symbols and philosophies, and reformulated, systematized and integrated into the coherent corpus of what became known as the tantra tradition. These two poles of values and rituals coexist and mutually penetrate each other in complex ways."
