Tantra (Sanskrit: तन्त्र; literally “loom, weave”) denotes 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.
