The oldest Pali writings are of great interest to the psychologist, not only because their analysis of mind is in many ways comparable to his own, but because their teaching has been used for practical purposes with enviable success. One of the most important of the Buddhist concepts is that of Nirvana, or nibbāna, whose modern usage has caused discomfort to many Buddhists, especially those of the Western world. Originally the name for a certain state of mind, and of personality, it has now acquired a multitude of definitions so heterogeneous and contradictory that few people know what to make of it.

Originally published in 1969, The Psychology of Nirvana was the first attempt to fit all the diffuse explanations and pronouncements of the oldest scriptures together into a consistent picture, and to relate this picture to modern Western psychology at the time. Just as Nirvana is a psychological state and the natural goal of Buddhism, mental health is the ideal of psychology. A comparative study of the two provides a book truly fascinating to scholars of psychology and Buddhism.
