The Great Vehicle teaches that all living beings will attain the enlightenment of the Buddha, become Buddhas themselves, and be freed from sufferings. Suppose, however, that someone were to attain enlightenment, but only for his own sake and not for the sake of others. This achievement would be in the narrow-minded and selfish spirit of the Lesser Vehicle. The Great Vehicle, on the other hand, teaches not individual, but universal salvation: all should equally attain the enlightenment of the Buddha. The words, “And may we and all other living beings Attain the enlightenment of the Buddha!” express this merciful yearning of the Great Vehicle for universal salvation—for the salvation of all beings without exception.
