"Do thy best; that is best. Leave unto thy Lord the rest." CHAPTER VIII THE TRAINING OF THE MIND AND THE PRACTICE OF MEDITATION 1. The Method of Instruction Adopted by Zen Masters. Thus far we have described the doctrine of Zen inculcated by both Chinese and Japanese masters, and in this chapter we propose to sketch the practice of mental training and the method of practising Dhyana or Meditation. Zen teachers never instruct their pupils by means of explanation or argument, but urge them to solve by themselves through the practice of Meditation such problems as--'What is Buddha?' What is self?' 'What is the spirit of Bodhidharma?' 'What is life and death?' 'What is the real nature of mind?' and so on. Ten Shwai (To-sotsu), for instance, was wont to put three questions[FN#229] to the following effect: (1) Your study and discipline aim at the understanding of the real nature of mind. Where does the real nature of mind exist? (2) When you understand the real nature of mind, you are free from birth and death. How can you be saved when you are at the verge of death? (3) When you are free from birth and death, you know where you go after death. Where do you go when your body is reduced to elements? The pupils are not requested to express their solution of these problems in the form of a theory or an argument, but to show how they have grasped the profound meaning implied in these problems, how they have established their conviction, and how they can carry out what they grasped in their daily life. [FN#229] The famous three difficult questions, known as the Three Gates of Teu Shwai (To Sotsu San Kwan), who died in 1091. See Mu Mon Kwan, xlvii.
