Vajradhara

'Diamond-holder'; Tibetan: རྡོ་རྗེ་འཆང, Wylie: rdo rje 'chang, THL: Dorje Chang; Chinese: 金剛總持; pinyin: Jīngāng zǒng chí; Javanese: Kabajradharan; Japanese: 持金剛仏; Vietnamese: Kim Cang Tổng Trì) is the ultimate primordial Buddha, or Adi-Buddha, according to the Sakya,[1] Gelug and Kagyu schools of Tibetan Buddhism.

He is depicted as dark blue in color, expressing the quintessence of buddhahood itself and representing the essence of the historical Buddha's realization of enlightenment.

Tantras are texts specific to Tantrism and are believed to have been originally taught by the Tantric form of Sakyamuni called Buddha Vajradhara.

The Trikaya doctrine (Sanskrit, literally "Three bodies or personalities"; 三身 Chinese: Sānshēn, Japanese: sanjin) is an important Buddhist teaching both on the nature of reality, and what a Buddha is.

In the Dzogchen tantric text rendered in English as "Shining Relics" (Tibetan: སྐུ་གདུང་འབར་བ, Wylie: sku gdung 'bar ba), an enlightened personality entitled Buddha Vajradhara and a Dakini whose name may be rendered into English as "Clear mind" engage in discourse and dialogue which is a common convention in such esoteric Buddhist literature and tantric literature in general.
