"The Buddhas, the World-Honored Ones, for one great cause alone appear in the world. The Buddhas, the World-Honored Ones, appear in the world because they wish to cause the beings to hear of the Buddha's knowledge and insight and thus enable them to gain purity. They appear in the world because they wish to demonstrate the Buddha's knowledge and insight to the beings. They appear in the world because they wish to cause the beings to understand. They appear in the world because they wish to cause the beings to enter into the path of the Buddha's knowledge and insight."
