Toh 240The Sūtra of the Wheel of No Reversions

THE SŪTRA OF THE WHEEL OF NO REVERSIONS (Avaivartacakrasūtra)

Background

The Sūtra of the Wheel of No Reversions (Avaivartacakrasūtra, Toh 240) is an important scripture of the Northern Buddhist Canon, preserved in the Kangyur—the Tibetan collection of the Buddha’s teachings. This sūtra places particular importance on the concept of the “avaivartin” (nonretrogression), referring to bodhisattvas who have committed themselves irrevocably to the bodhisattva path of practice and never again turn back to the narrower path of the Lesser Vehicle.

Within the context of the Mahayana teachings, this sūtra belongs to a powerful tradition emphasizing bodhicitta (the mind of awakening)—the aspiration to liberate immeasurable sentient beings. In Buddhism, the image of the wheel (cakra) symbolizes the movement of the Buddha’s Dharma and the continuous transmission of the teachings. The wheel of no reversions symbolizes uninterrupted progress, without retreat, upon the bodhisattva path—an everlasting commitment to the welfare of sentient beings.

Principal Content

This sūtra focuses on the fundamental characteristics of “nonretrogressing” bodhisattvas—those who have vowed irrevocably to practice the Mahayana path and never fall prey to obstacles. In the Northern Buddhist Canon, “no reversions” is not merely a psychological state but a profound ontological commitment, defined by the five infinities or the immeasurable worlds of the ten directions in the Mahayana.

The sūtra affirms that once bodhisattvas have genuinely aroused bodhicitta and perceived the emptiness (śūnyatā) of all dharmas, their minds become like a wheel that turns endlessly without stopping—always directed toward the liberation of all sentient beings. This is the fruit of awakening born from wise understanding of pratītyasamutpāda (dependent origination), the foundation of the entirety of Buddhist philosophy.

The sūtra also emphasizes that nonretrogressing bodhisattvas are protected by the attestation of the Buddha and all bodhisattvas of the three times. They are supported by devas and by the power of their own practice accumulated throughout immeasurable eons. Boundless compassion (karuṇā and mahākaruṇā) is their unstoppable driving force.
