An Explanation of the Scripture of the Vow of the Naga Vajratunda
Background
The Scripture of the Vow of the Naga Vajratunda (Vajratundanagasamaya) is recorded in the Kangyur of the Northern Tibetan tradition, reflecting an important foundation of Tibetan Mahayana Buddhism, where Buddhist deities, local divinities, and other kinds of beings are all present in the field of practice of spiritual practitioners.
The naga Vajratunda is a dragon deity regarded as a protector of the Buddha Dharma, possessing supernatural power and tremendous spiritual force. The name “Vajratunda” (skillful thunder-root, or the firm thunder dragon) indicates that this deity possesses an indestructible nature, closely connected with the supreme power of the truth of the Buddha Dharma. In the Tibetan Buddhist tradition, such dragon deities are often invoked to act as Dharma protectors, standing beside practitioners and other spiritual communities.
The background of this scripture arises from a basic principle of Tibetan Mahayana: all deities, spirits, and beings are expected to commit themselves to the Three Jewels (Buddha, Dharma, and Sangha) through solemn vows, in order to protect the Buddha Dharma and support practitioners on the path to awakening.
Main Content
This scripture records the solemn vow of the naga Vajratunda, a profound commitment dedicated to protecting the Buddha Dharma in the world. The naga Vajratunda vows that he will not cause droughts, floods, or natural disasters in lands where the Buddha Dharma is practiced. This dragon deity also commits to helping practitioners obtain favorable conditions for practice, protecting them from obstacles and misfortunes.
The vow is not merely a set of abstract promises, but consists of concrete and practical effects. The naga Vajratunda commits to acting as an invincible special force, not allowing egoic forces (mara, forces that obstruct awakening) to harm places where the true Buddha Dharma is practiced.
🌏 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.
