yāna ［乗］ (, Pali;  jō): A vehicle. In general, any kind of vehicle, such as a boat, cart, or carriage. In Buddhism, yāna indicates a Buddhist teaching that “carries” or “transports” people to a particular level of enlightenment. It is a component of a number of Buddhist terms, such as mahāyāna (great vehicle), hīnayāna (lesser vehicle), ekayāna (one vehicle, or supreme vehicle), buddha-yāna (Buddha vehicle), bodhisattva-yāna (bodhisattva vehicle), pratyekabuddha-yāna (cause-awakened one vehicle), and shrāvaka-yāna (voice-hearer vehicle). Shrāvaka-yāna, pratyekabuddha-yāna, and bodhisattva-yāna are collectively called tri-yāna, or the three vehicles.
