Tantra (Sanskrit: ; "weave" denoting continuity), (anglicised tantricism or tantrism) or tantram (Sanskrit) is a religious philosophy according to which Shakti is usually the main deity worshipped, and the universe is regarded as the divine play of shakti and shiva. The word Tantra also applies to any of the scriptures commonly identified with the worship of Shakti. Tantra deals primarily with spiritual practices and ritual forms of worship, which aim at liberation from ignorance and rebirth. The tantric movement has influenced the Hindu, Bön, Buddhist, and Jain religious traditions. Tantra in its various forms has existed in India, Nepal, China, Japan, Tibet, Korea, Cambodia, Burma, Indonesia and Mongolia. Although he cautions against attempting a rigorous definition of tantra, David Gordon White offers the following definition:
Tantra is that Asian body of beliefs and practices which, working from the principle that the universe we experience is nothing other than the concrete manifestation of the divine energy of the Godhead that creates and maintains that universe, seeks to ritually appropriate and channel that energy, within the human microcosm, in creative and emancipatory ways.
Part 1: The Basic of Tantrism
Tantra has been one of the most neglected branches of Indian spiritual studies despite the considerable number of texts devoted to this practice, which dates back to the 5th-9th century AD.
Many people still consider tantra to be full of obscenities and unfit for people of good taste. It is also often accused of being a kind of black magic. However, in reality, tantra is one of the most important Indian traditions, representing the practical aspect of the Vedic tradition.
The religious attitude of the tantriks is fundamentally the same as that of the Vedic followers. It is believed that the tantra tradition is a part of the main Vedic tree. The more vigorous aspects of Vedic religion were continued and developed in the tantras. Generally tantriks worship either Goddess Shakti or Lord Shiva.
