An ivory vishvavajra

COMMENT. Vishvavajra is the Sanskrit name for the crossed vajra (Tibetan: rdo rje rgya gram; Bhutanese: dorji jadam), which is a symbolic weapon, a ritual object, an amulet and an attribute of some deities in Tibetan Tantric (Esoteric) Buddhism. It is formed from four lotus-mounted vajra heads that emanate from a central hub towards the four cardinal directions. Vishvavajra represents the principle of absolute stability of the physical world, therefore it is also called the "universal" vajra. Along with ordinary vajra, it occupies an extremely important place in Vajrayana (literally the "Diamond Vehicle" or the "Thunderbolt Vehicle"), the Tantric school of Tibetan Buddhism. In addition, the crossed vajra is part of the emblem of Bhutan.
