Trikaya

Lore & Background

The Trikāya doctrine was developed in early Yogācāra school sources, such as the Mahāyāna-sūtrālamkāra. It explains how a Buddha can simultaneously exist in multiple realms and embody a spectrum of qualities and forms, while also appearing in the world with a human body that gets old and dies (though this is merely an appearance). The doctrine is also used to explain the Mahayana concept of non-abiding nirvana (apratiṣṭhita-nirvana), which sees Buddhahood as both unconstructed and transcendent, as well as constructed, immanent, and active in the world. Mahayana sources emphasize that the three bodies are ultimately non-dual, but can be described differently due to their relative functions or activities. The Buddhabhūmi-vyākhyāna states that the body of the Tathagatas is undivided, yet functions as distinguished into three embodiments. The Trikāyasūtra provides a simile: the dharmakāya is like the sky, the saṃbhogakāya like a cloud, and the nirmāṇakāya like rain. The Golden Light Sutra associates different kinds of wisdom with each body and with the eight consciousnesses.

Reader's Guide

The Trikāya doctrine is a cornerstone of Mahayana and Vajrayana teachings, providing a comprehensive perspective on the nature of Buddhahood, Buddhist deities, and the Buddhist cosmos. It explains how a Buddha can be both transcendent and immanent, free from worldly conditions yet compassionately manifesting for the good of all beings. The doctrine's interpretations vary across different Buddhist traditions, with some theories containing extra 'bodies,' making it a 'four body' theory and so on. However, the basic Trikāya theory remains fundamental. The doctrine was also adopted into Daoist philosophy and modified using Daoist concepts. The relationship among the three bodies is described in various sources: the Dharmakāya is the primary and ultimate Buddha body, the foundation and basis for the two other bodies. The Sambhogakāya is multiple, appearing in many forms according to the aspirations of beings, while the Nirmāṇakāya is singular, appearing as one form. The Dharmakāya is neither singular nor multiple, 'neither the same nor different.' The Buddhabhūmi-vyākhyāna explains that only Buddhas see the dharma body, only bodhisattvas see the enjoyment body, and sentient beings see the manifestations.
