Systems for promoting self-realization have come both from the West and the East. Two basically Eastern systems of ``therapy," in the Zen tradition and the Hindu Yoga meditative tradition, are now attracting substantial interest in the West. There is now substantial Western concern to evaluate their effectiveness in the way that many other psychotherapeutic traditions have been examined. In particular a technique in the Hindu Yoga meditative tradition, Transcendental Meditation (TM) is beginning to attract strong scientific attention in the West. This paper looks at some of the physiological, psychological and social research on this practice, and also looks at some of the rather arresting work done in the training of people to produce states of mind found subjectively to be pleasent. This paper then is concerned to look at some of the correlates of states of "human realization."
