Three Vajras

The Three Vajras, namely "body, speech and mind", are a formulation within Vajrayana Buddhism and Bon that hold the full experience of the śūnyatā "emptiness" of Buddha-nature, void of all qualities (Wylie: yon tan) and marks (Wylie: mtshan dpe) and establish a sound experiential key upon the continuum of the path to enlightenment. The Three Vajras correspond to the trikaya and therefore also have correspondences to the Three Roots and other refuge formulas of Tibetan Buddhism. The Three Vajras are viewed in twilight language as a form of the Three Jewels, which imply purity of action, speech and thought.

The Three Vajras are often mentioned in Vajrayana discourse, particularly in relation to samaya, the vows undertaken between a practitioner and their guru during empowerment. The term is also used during Anuttarayoga Tantra practice.

In Tendai and Shingon Buddhism of Japan, they are known as the Three Mysteries (三密, sanmitsu^?).

The Three Vajras is an English rendering of gsang ba gsum (Tibetan); which has variously been rendered as: Three Secrets, Three Mysteries, Three Seats, Three Doors and Three Gateways. Another Tibetan orthography that explicitly mentions Vajra (Tibetan: rdo-rje) is: rdo rje gsang ba gsum. The full Tibetan title may be rendered into English as 'the three secrets of the noble ones' (Tibetan: phags pa'i gsang ba gsum) which are: body (Tibetan: lus and sku); voice/speech (Tibetan: gsung) and mind (Tibetan: thugs). Another full title: sku gsung thugs mi zad pa rgyan gyi 'khor lo may be rendered as "Inexhaustible adornment wheel of Body, Speech and Mind" where the term 'khor lo is the Tibetan term for chakra (Sanskrit).
