Tantra is a vast ocean of wisdom for enlightening the mind. It is not merely sex, with which most Westerners identify it, but an Indian philosophy that includes sexuality as a minor factor and an entire science of meditation. Tantric Yoga and the Wisdom Goddesses describes the deeper system of Tantra in its psychological and spiritual sophistication - unfolding the mysteries of life and death, being and non-being. It reveals Tantra as a profound methodology for reaching the highest states of consciousness.
Tantra is a powerful substream of Hindu teachings, outside both orthodox
Hinduism and the six classical schools of Indian philosophy, but non-the-less,
deeply embedded in the matrix of Hinduism. Tantra treats five subjects:
(of worlds) 3-worship of Goddesses; 4-attainment
of all objects; 5-the four modes of union
with the supreme by meditation.
