Toh 841aA Fragment from the Vajrakīlaya Root Tantra

An Exposition of an Excerpt from the Vajrakīlaya Root Tantra

Context

Vajrakīlaya, or the “Vajra Nail” (Dorje Phurba in Tibetan), is one of the most important deities of Vajrayana Tantra, especially in the Nyingma tradition of Tibetan Buddhism. This excerpt is preserved in the Kangyur, the Tibetan Buddhist canon compiled from the eighth century onward, for the purpose of preserving the original tantric teachings in Tibetan.

The Vajra Nail is not a physical implement, but a symbol of directly piercing through psychological obstacles, defilements, and negative forces. In the tantric context, it represents sharp wisdom (prajñā), capable of destroying ignorance—the root source of all suffering. The Vajrakīlaya Root Tantra contains detailed esoteric methods (sādhana) for practicing this divine form, combining the power of mantra, ritual gestures (mudra), and symbols (yantra) to transform the mind.

Main Content

Although this excerpt is part of a larger work, the teachings of the Vajrakīlaya Root Tantra focus on the complete process of diligent practice. The Tantra teaches that the sacred aspect of Vajrakīlaya embodies the activity of subjugation (carana), one of the five principal tantric activities (gos-kyi las-lngas).

The original content describes how to visualize the form of the Vajra Nail, commonly envisioned with three faces, three arms, and two legs, expressing the pervasiveness of the three spheres—wisdom, means, and activity—and the comprehensive application of tantric principles. The text teaches practices of assuming the identity of Vajrakīlaya, using the mantra OM AH HUNG to activate the energy centers (chakra) within the subtle body.

In particular, this Tantra emphasizes the principle of emptiness (śūnyatā): that all phenomena are empty of fixed nature.
