Etymology[edit]
According to Jan Nattier, the term Mahāyāna ("Great Vehicle") was originally an honorary synonym for Bodhisattvayāna ("Bodhisattva Vehicle")[5] — the vehicle of a bodhisattva seeking buddhahood for the benefit of all sentient beings.[2] The term Mahāyāna was therefore formed independently at an early date as a synonym for the path and the teachings of the bodhisattvas. Since it was simply an honorary term for Bodhisattvayāna, the creation of the term Mahāyāna and its application to Bodhisattvayāna did not represent a significant turning point in the development of a Mahāyāna tradition.[5]
The earliest Mahāyāna texts often use the term Mahāyāna as a synonym for Bodhisattvayāna, but the term Hīnayāna is comparatively rare in the earliest sources. The presumed dichotomy between Mahāyāna and Hīnayāna can be deceptive, as the two terms were not actually formed in relation to one another in the same era.[6]
Among the earliest and most important references to the term Mahāyāna are those that occur in the Lotus Sūtra (Skt. Saddharma Puṇḍarīka Sūtra) dating between the 1st century BCE and the 1st century CE.[7] Seishi Karashima has suggested that the term first used in an earlier Gandhāri Prakrit version of the Lotus Sūtra was not the term mahāyāna but the Prakrit word mahājāna in the sense of mahājñāna (great knowing).[8][9] At a later stage when the early Prakrit word was converted into Sanskrit, this mahājāna, being phonetically ambivalent, was mistakenly converted into mahāyāna, possibly because of what may have been a double meaning in the famous Parable of the Burning House, which talks of three vehicles or carts (Skt: yāna).[note 2][8][10]
