Ekayāna

Ekayāna (traditional Chinese: 一乘; pinyin: Yīchéng; Japanese: いちじょう; Korean: 일승) is a Sanskrit word that can mean "one path" or "one vehicle". It is used both in the Upanishads and the Mahāyāna sūtras.

In the Brihadaranyaka Upanishad, "ekayāna" took on special significance as a metaphor for a spiritual journey. The phrase vedānāṃ vāk ekayānam translates approximately to "the one destination of the Vedas is the spirit of the word".

Early Buddhist texts such as the Satipaṭṭhāna Sutta use the term 'ekāyano maggo' to refer to the Four Satipatthanas. While some have translated this as the "one path" (to nirvana), a better translation would be "the direct path".'

Ekayāna sutras of primary influence are the Lotus Sutra, the Śrīmālādevī Siṃhanāda Sūtra, the Ratnagotravibhāga and the Tathāgatagarbha sūtras, which also include the Tathāgatagarbha Sūtra, the Mahāyāna Mahāparinirvāṇa Sūtra and the Aṅgulimālīya Sūtra. Sutras with similar teachings include the Laṅkāvatāra Sūtra and the Avatamsaka Sutra. The Lotus Sutra declares that "the three vehicles of the Śrāvaka (disciple), Pratyekabuddha (solitary buddha), and Bodhisattva are actually just three expedient devices (upayacausalya) for attracting beings to the one buddha vehicle, via which they all become buddhas."
