The Vajra, or diamond scepter (thunderbolt) is a powerful emblem of sovereignty -it has the indestructible qualities of the diamond, able to overcome anything that crosses its path.

There are two forms of the Vidya most commonly associated with Mahavairocana - a va ra ha kham and a vi ra hum kham. In the center is the seed syllable elaborate 'ahm', the very top is plain 'ah'. The Vajra dhatu (diamond realm) represents the wisdom or consciousness aspect of Virocana. In the Gharbhakosa (lit. womb store) dhatu, the Vidya has a complex range of associations but are strongly connected with the 5 elements(dhatu) of earth(prithvi), Water(apas), Fire(agni), Air(vayu), and Space(akasha). Mahavairocana himself represents the 6th element that completes the set of elements which make up all of the universe: ie consciousness. Individual person, animal, plant or matters are all like cells which make up part of the universe, thus the whole universe is the Tathāgata's Gharbha (womb).
