Tantra (from the Sanskrit root tan — to expand, to weave) refers to a broad family of spiritual traditions — Hindu and Buddhist — that arose approximately in the 5th-9th centuries CE and offered a radical alternative to the mainstream renunciate spirituality of classical Hinduism and early Buddhism. Where the mainstream traditions emphasised withdrawal from the world, suppression of desire and the transcendence of embodied existence, Tantra insisted that the world, the body and all of experience are manifestations of the divine — and that liberation is found through transformation and recognition rather than rejection.
The foundational Tantric insight: the universe is the self-expression of divine consciousness (Shiva) through divine energy (Shakti). These are not two separate principles but one reality experienced from two perspectives — Shiva as the unchanging awareness, Shakti as its dynamic creative power. The human being participates in this divine dynamic — consciousness expressing itself through the energetic vehicle of the body-mind. Liberation (moksha) is the recognition of this participation — not the escape from it.
