— Mahaparinabbana sutta
Therefore, Ananda, be ye lamps unto yourselves, be ye a refuge to yourselves. Betake yourselves to no external refuge. Hold fast to the Truth as a lamp; hold fast to the Truth as a refuge. Look not for a refuge in anyone besides yourselves. And those, Ananda, who either now or after I am dead shall be a lamp unto themselves, shall betake themselves to no external refuge, but holding fast to the Truth as their lamp, and holding fast to the Truth as their refuge, shall not look for refuge to anyone beside themselves—it is they who shall reach the very topmost height. But they must be anxious to learn.
