Yoga tantras

This text is classified as a Yogatantra. In India, this tantra was originally united with the following text in the Kangyur (Toh 488) as a single text. But in the Tibetan Kangyur they are represented as two individual texts, since different teams of translators rendered the two parts into Tibetan at different times. The teacher of the tantra is Vairocana. In this text the Buddha Vairocana first teaches seventeen pure states observed by bodhisattvas as they accomplish the perfection of insight. Next, over twelve chapters, Vairocana emanates a large number of maṇḍalas and he reveals the rituals and practices associated with these awakened environments.

This text is classified as a Yogatantra. In India, this tantra was united with the previous text in the Kangyur (Toh 487) as a single text. But in the Tibetan Kangyur they are represented as two individual texts, since different teams of translators rendered the two parts into Tibetan at different times. The teacher of the tantra is Vairocana but the rituals also focus on the Buddha Vajrasattva. This latter part of the tantra is longer and consists of forty-four chapters that together comprise the second, third, and fourth sections of the larger work. As such, although it is called the “Chapter on Mantras” it covers many additional instructions. First, a lengthy description is given of the benefits that arise from the practice of the perfection of wisdom as taught in the first part of the tantra. In the remainder of the tantra, the Buddha Vajrasattva emanates the maṇḍalas taught earlier in the text and he teaches in great detail about their connected rituals.
