Buddhism and Buddhists in China

There are in the world at least three classes of men. The lowest class live among material things, they are occupied with possessions. Their life is entangled in the crude and coarse materials which they regard as real. A second, higher class, regard ideas as realities. They are not entangled in the maze of things, but are confused by ideas, ascribing reality to them. The third and highest class are those who by meditation have freed themselves from the thraldom of ideas and can enter the sixteen heavens.
