What to read after Manual of Zen Buddhism?

Here are the famous sutras, or sermons, of the Buddha, the gathas, or hymns, the intriguing philosophical puzzles known as koan, and the dharanis, or invocations to expel evil spirits. Included also are the recorded conversations of the great Buddhist monks—intimate dialogues on the subjects of momentous importance. In addition to the written selections, all of them translated by Dr. Suzuki, there are reproductions of many Buddhist drawings and paintings, including religious statues found in Zen temples, each with an explanation of its significance, and the great series of allegorical paintings “The Ten Oxherding Pictures.”
