The Great Vehicle is a major strand of which religion?

Mahāyāna ("Great Vehicle") is one of two main existing branches of Buddhism (the other being Theravada) and a term for classification of Buddhist philosophies and practice. This movement added a further set of discourses, and although it was initially small in India, it had long-term historical significance. The Buddhist tradition of Vajrayana is sometimes classified as a part of Mahāyāna Buddhism, but some scholars consider it to be a different branch altogether.

"Mahāyāna" also refers to the path of the Bodhisattva seeking complete enlightenment for the benefit of all sentient beings, also called "Bodhisattvayāna", or the "Bodhisattva Vehicle". A bodhisattva who has accomplished this goal is called a samyaksaṃbuddha (सम्यक्सम्बुद्ध), or "fully enlightened Buddha". A samyaksaṃbuddha can establish the Dharma and lead disciples to enlightenment. Mahāyāna Buddhists teach that enlightenment can be attained in a single lifetime, and this can be accomplished even by a layperson.
