Now Mahayana Buddhism actually encompasses a very large set of various practices, but the general idea is that you might have help as you try to achieve nirvana. Someone who achieves nirvana is known as an arhat. So you could view Theravada Buddhism as, hey, try to go on this personal journey to become an arhat, to achieve nirvana. But in Mahayana Buddhism, the pursuit is not necessarily to get to nirvana as quickly as possible. It's to get close to nirvana, but then help others try to achieve that same state. So the real goal is to be a bodhisattva. Bodhisattva.
