The narrative … told by the four sravakas is called the “Parable of the Rich Man and His Poor Son.” As we can see from what they have said, the Lesser Vehicle which they had been following stressed escape from this world of sorrows into a pure world of contemplation. Its concept of enlightenment was also passive. It concluded that “nothing is different from anything else,” and “there is nothing more to seek.” This view rejected the reality of this world and the necessity of working to change it. The Great Vehicle, on the other hand, interpreted the same doctrine [that nothing is substantial] positively as becoming a buddha in this world and transforming it into a buddha-world. Enlightenment is to be achieved within the turmoil of our daily life, not in silent seclusion. The four “hearers” now realize that they, too, have obtained the wonderful law of the Great Vehicle and have departed from the passivity of the Lesser Vehicle.
