Eastern psychology and Western psychology have been operating on the basis of different theoretical orientations. This paper examines both Western and Eastern psychological theories and clinical practices to understand commonly experienced spiritual phenomena, particularly those rooted in the traditional Asian beliefs. The following theoretical and practice approaches are discussed in this paper: Drive Theory, Ego Psychology, Object Relations, Self Psychology and Inter-subjectivity, as well as Eastern theoretical and practice approaches, such as Buddhist and Taoist psychology. While theories and practices are still evolving, two or more theories and practice approaches may be integrated to fit unique needs of populations from diverse cultural and spiritual backgrounds.
