Marvin Levine, a well-known researcher and theorist in cognitive-experimental psychology, received his M.A. at Harvard where he worked with B.F. Skinner and George Miller, and his Ph.D. with Harry Harlow at the University of Wisconsin. Since 1965 he has been a professor in the Department of Psychology at Stony Brook University. His earliest work was on intellectual problem solving, research that served to counter the then popular conditioning view of human behavior. He later turned his attention to interpersonal problem solving, giving workshops on assertiveness training and anger management, and for several years helped resolve disputes as a volunteer mediator. He is also a published poet and a professional musician. As is revealed in this volume, all these activities have contributed to his understanding of human nature. He also maintained a long-standing interest in Eastern philosophy. He gradually began to see similarities between the conceptions and methods of Buddhism and Yoga and those of Western psychotherapy. In this accessible book he discusses these three systems. The exotic and "mystical" trappings from Buddhism and Yoga are stripped away. The emphasis, instead, is on their aims and methods, and their relation to Western psychology. This approach provides a clear understanding of how to live a more useful, happier life. It is also an essential read for anyone interested in an enlarged framework for modern psychology.
