Our perception of reality is highly conditioned by constitutional and cultural variables. What is the nature of this conditioning and how does it contribute to illness? What are the qualities of the authentic self, that best part of us that is always free from conditioning? In this talk I will distinguish between the ego and the authentic self and discuss their relationship to health, illness, and healing. I will make distinctions between the mind, soul, spirit, conscience, ego, and authentic self within the context of medicine. I will then take questions for 20 minutes.
