The process of mind-development is considered by Buddhist thought to be the highest step on the path to spiritual perfection. Concentration first brings the mind under exacting control. Then through the arduous progression from lower Meditation to higher Meditation and finally to Contemplation the highest form of enlightenment is reached. Here are the basic principles of mind-development presented by a leading figure in world Buddhism. No knowledge of Buddhist thought is necessary to understand these teachings. The student is guided through successive levels of Concentration and Meditation. Physical and mental exercises, the objects of thought, and underlying philosophical ideas are described at every stage. The ultimate aim of this progressive course in mind-development is to bring the student to a point of spiritual attainment beyond which this or any other text would not presume to lead.
