An Exposition of the Sarvatathāgatatattvasaṅgraha
Context
The Sarvatathāgatatattvasaṅgraha, also called the Vajraśekhara Tantra, is one of the foundational scriptures of Yoga Tantra, the third of the four classes of Tantra in the Vajrayana tradition. This scripture was translated from Sanskrit during the flourishing development of Esoteric Buddhism in India, around the eighth to ninth centuries.
The title reflects the whole essential message: "Sarvatathāgata" — all Tathagatas; "tattva" — ultimate reality; and "saṅgraha" — collection or means. This is a scripture oriented toward the practice of Yoga Tantra, in which monastic practitioners begin to contemplate the whole truth of the Buddhadharma through mandala imagery and systematic rules of practice.
This scripture is regarded as the source giving rise to the Vajradhātu-maṇḍala, the diagram of the spiritual cosmos in which Buddhas and bodhisattvas manifest different aspects of awakening.
Main Content
The Sarvatathāgatatattvasaṅgraha focuses on teaching how to recognize that all sentient beings and phenomena contain the very nature of the Tathagatas. This is not at the theoretical level, but at the level of direct practice through imagery.
The scripture teaches that through Yoga Tantra, the practitioner does not seek the Buddha outside, but realizes that one’s own mind is the Buddha mind. The Vajradhātu Mandala is not a drawing outside the physical world; it is a representation of the divisions of categories of truth and methods of practice. The Buddha mind, Vairocana, is at the center, surrounded by Buddha realms and bodhisattvas, each representing an aspect of awakening — clarity, compassion, wisdom, and liberating action.
The scripture emphasizes that there is nothing in this universe that is separate.
🌏 The Buddhist canon is vast — some sūtras (such as comparative Vinaya across schools, or untranslated Tibetan-canon texts) have to this day NEVER been translated into Vietnamese or English by anyone, scholars included. Rather than leave it blank, Inti AI offers a FAITHFUL summary grounded in the tradition — from the sūtra's title, origin and essence — so you can still reach this rare part of the treasury. Whenever an original translation exists, the app shows the original first.
