Hindu tantra

Tantra (Sanskrit: तन्त्र; literally "loom, weave") is the esoteric traditions of Hinduism and Buddhism that co-developed most likely about the middle of 1st millennium CE. The term tantra, in the Indian traditions, also means any systematic broadly applicable "text, theory, system, method, instrument, technique or practice".

In Hinduism, the tantra tradition is most often associated with its goddess tradition called Shaktism, followed by Shaivism and Vaishnavism. In Buddhism, the Vajrayana tradition is known for its extensive tantra ideas and practices. Tantric Hindu and Buddhist traditions have influenced other religious traditions such as Jainism, Sikhism, the Tibetan Bön tradition, Daoism, and the Japanese Shintō tradition.

Tantra as genre of literature in Hinduism have been influential to its arts, icons and temple building practices. Hindu puja, temples and iconography are tantric in nature. The Hindu texts that describe these topics are called Tantras, Āgamas or Samhitās. In Buddhism, its tantra-genre literature has influenced the artworks in Tibet, historic cave temples of India, and imagery in southeast Asia.

Tantra (Sanskrit: तन्त्र) literally means "loom, warp, weave".

The connotation of the word tantra to mean an esoteric practice or religious ritualism is a colonial era European invention. The term is based on the metaphor of weaving, states Ron Barrett, where the Sanskrit root tan means the warping of threads on a loom. It implies "interweaving of traditions and teachings as threads" into a text, technique or practice.

The word appears in the hymns of the Rigveda such as in 10.71, with the meaning of "warp (weaving)". It is found in many other Vedic era texts, such as in section 10.7.42 of the Atharvaveda and many Brahmanas. In these and post-Vedic texts, the contextual meaning of Tantra is that which is "principal or essential part, main point, model, framework, feature". In the Smritis and epics of Hinduism (and Jainism), the term means "doctrine, rule, theory, method, technique or chapter" and the word appears both as a separate word and as a common suffix, such as atma-tantra meaning "doctrine or theory of Atman (soul, self)".
