 Both historically and doctrinally, the principal difference between the Theravāda and the Mahāyāna lies in the goals they recommend. Most Theravāda practitioners aspire to become Saints (Skt. Arhat, Pāli Arahant). The life in which someone becomes a Saint is that person’s last life; this person will no longer be reborn, but will instead enter Nirvana at death. A small minority of Theravādins, however, aspire to become Buddhas. As they understand that goal, a Buddha is someone who rediscovers the truths of Buddhism after they have been lost to the world, and teaches them to others so as to benefit them. The Theravāda tradition maintains that, like Saints, Buddhas pass into Nirvana at death. Becoming a Buddha is believed to be more difficult and take more time than becoming a Saint; it is a demanding path for a small minority. A practitioner who is on the way to becoming a Buddha is known in Sanskrit as a bodhisattva (Pāli bodhisatta).
