Transpersonal psychology stands at the interface of psychology and spiritual experience.
It is the field of psychology which integrates psychological concepts, theories, and methods with the subject matter and practices of the spiritual disciplines. Its interests include spiritual experiences, mystical states of consciousness, mindfulness and meditative practices, shamanic states, ritual, the overlap of spiritual experiences and disturbed states such as psychosis and depression, and the transpersonal dimensions of relationships, service, and encounters with the natural world. The central concept in Transpersonal Psychology is self-transcendence, or a sense of identity which is deeper, broader, and more unified with the whole. Rather, it is a field of inquiry which offers insights based on research and experience and provides practices for evaluating and confirming or disconfirming its findings. Transpersonal psychology has benefits for both psychology and the spiritual disciplines.
