Vajrasekhara Sutra

[2] The tantra begins with Vairocana Buddha preaching the Dharma to a great host of Bodhisattvas, including Vajrasattva, in the Pure Land of Akanishta.

As he preaches the Dharma, Prince Sarvarthasiddhi, the esoteric name of the Buddha, Siddhartha Gautama, is meditating under the Bodhi Tree.

Despairing over his inability to find Enlightenment, he is visited by Buddhist figures who were just now learning the Dharma from Vairocana.

This tantra also introduces the Diamond Realm Mandala as a focus for meditative practices, and its use in the abhiseka ritual of initiation.

In tantric ritual, the teacher assumes the role of the Prince who constructs the Mandala, while the master and student repeat specific mantras in a form of dialogue.
