Transpersonal Psychology addresses the spiritual nature of humankind. Unlike religion and theology, its interest centres on the mind and behaviour; hence it is a branch of Psychology.
All the major spiritual and mystical traditions of the world incorporate teachings about the nature of mind and promote behavioural practices intended – amongst other goals – to bring about psychological transformations. Transpersonal psychology addresses these teachings and practices, researching their value and evaluating their relationships to ideas promulgated in Psychology. In essence Transpersonal Psychology seeks to integrate non-scientific spiritual insights with observations and models associated with the rigorous methodological approach of psychological science.
