Toh 403Tantra of the Vajra King

Commentary on the Vajra King Sutra

Context

The Vajra King Sutra (Vajrarājamahātantra) is one of the foundational scriptures of Vajrayana Tantric Buddhism, recorded in the Kangyur, the collection of the Buddha’s discourses in tantric form. This sutra belongs to the system of advanced tantras, especially the king tantras (Rāja-tantra) in the Tibetan Buddhist tradition.

The name “Vajra King” is not ordinary, but refers to the supreme Buddha-nature manifested through the image of the vajra, the symbol of invincibility, permanence, and fearlessness. This sutra was transmitted from the twofold Buddha-nature (Dharmakāya) down to noble beings and practitioners of suitable capacity, according to the rules of secrecy in the Tantras. Therefore, this sutra is taught only to those who have received empowerment and have the bond of secret word (samaya) with their root teacher.

Main Content

The Vajra King Sutra presents advanced principles of tantric practice, including: (1) meditation on sacred deities (yidam), with the body as an illusion, without independent essence; (2) the generation stage and the completion stage, joined with wind, bliss, and the mind of liberation; (3) methods for controlling subtle energy within the body’s energy channels (nāḍī) in order to activate innate clarity.

This sutra emphasizes that Buddha-nature is not something foreign that must be attained, but the inherent nature of all sentient beings. Through practice according to the guidance of the root teacher, the practitioner gradually recognizes this nature through deep meditation, turning toward the hidden mechanism of mind and energy. When the goal is reached, the mind merges with the clear light, thereby awakening the state of supreme Buddha-nature.

Practical Meaning

For modern practitioners who have received tantric methods, the Vajra King Sutra guides the approach to one’s own Buddha-nature not through reasoning but through direct experience.
