Toh 284The Sūtra of the Three Heaps

An Explanation of the Sūtra of the Three Heaps

Background

The Sūtra of the Three Heaps (Triskandhakasūtra) is a scripture of the Northern Transmission canon, preserved in the Kangyur of Tibetan Buddhism. This sūtra holds a special place in the Mahāyāna tradition, especially in the foundation of practice of Tibetan schools such as Gelug, Nyingma, Kagyu, and Sakya.

The word “Triskandha” means “three heaps” or “three records,” referring to three causes and conditions (karma, space-time, and consciousness) through which actions are performed. The sūtra was composed to provide practical instructions on how to perform supplication, confession, and the cultivation of compassion.

In the context of Tibetan Buddhism, this sūtra is regarded as an important document for the work of confession (Tibetan: dugje ཞུགས་སྡུག་), an indispensable foundation on the Mahāyāna path of practice.

Main Content

The Sūtra of the Three Heaps focuses on three basic elements that constitute the power of ethical action:

The first is the heap of mind — the action of the mind, or intention (Pāli: cetanā; Sanskrit: cetanā). This is the pure or impure motivation behind our actions. The sūtra emphasizes that intention is the root of all actions that have results.

The second is the heap of speech — the action of speech. Speech is regarded as the bridge between mental intention and the outer world. The sūtra teaches the power of truthful speech, compassionate speech, and the way speech can spread merit or create harm.

The third is the heap of body — the action of the body. This is the physical expression of mental intention and speech, including actions of supplication, offering, and confession.

The sūtra emphasizes that these three heaps do not exist separately but are always organically related. A complete action must include these three elements harmoniously. For example, when practicing confession before the Buddha, there must be sincere intention (the heap of mind), verbal confession of wrongdoing (the heap of speech), and acts of reverence in the ten directions (the heap of body).
