What is the tantric practice in Tibetan Buddhism?

How is tantric Buddhism different?

Tantra (from Sanskrit: तन्त्र, "loom, weave, system") denotes the esoteric traditions of Hinduism and Buddhism that co-developed most likely about the middle of the 1st millennium AD. The term tantra, in the Indian traditions, also means any systematic, broadly applicable "text, theory, system, method, instrument, technique or practice". Starting in the early centuries of common era, newly revealed Tantras centering on Vishnu, Shiva or Shakti emerged.

In Buddhism, the Vajrayana tradition is known for its extensive tantra ideas and practices. Tantric Hindu and Buddhist traditions have influenced other Eastern religious traditions such as Jainism, the Tibetan Bön tradition, Daoism and the Japanese Shintō tradition.

Certain modes of non-vedic worship such as Puja are considered tantric in their conception and rituals. Hindu temple building also generally conforms to the iconography of tantra. 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.
