Psychological knowledge and know-how have been for many centuries the central focus of the Indian civilization. In this article it is argued that there is much in the various In-dian knowledge systems that deserves to be included in the psychology curriculum. To support this idea, three closely related aspects of the study of consciousness are dis-cussed in which the basic presumptions of the Indian tradition seem to have been more conducive to the production of valid and relevant knowledge and know-how than those of traditional western psychology. The first of these is the relation between subject and object, the second is the multi-dimensional nature of consciousness, and the third is yo-ga as a “technology of consciousness.” In the final section an indication is given of how a beginning could be made towards the systematic and institutionalized integration of the psychological knowledge from the major spiritual traditions with western psychology.
