Transpersonal Therapy
This is a growing sub-field or school of psychotherapy that integrates the spiritual and transcendent aspects of the human experience with getting well and accessing personal power.
Taking a transpersonal approach includes spiritual self-development and what that actually means in practice. You might, just as I was, be very surprised. The approach develops an understanding of self, beyond the ego, develops understanding of peak experiences of peace, contentment, serenity, bliss and enlightenment, and more importantly how to achieve this. It concerns itself with spiritual growth, what personal spiritual practices might look like, and what adopting such investigation and practice may mean for an expanded and empowered experience of living.
I have not seen any other therapy come close to achieving the outcomes of the transpersonal approach.
