The seat of our real mind is the subconscious. Joseph Murphy (in The Power of Your Subconscious Mind) wrote that we view our world through thoughts in the subconscious mind. Change your thought and you change your destiny. Ralph Emerson said that man is what he thinks all day long.
Debbie Shapiro wrote (in The Bodymind Workbook): Cancer appears to be the result of many years of inner conflict, guilt, hurt, grief, resentment, confusion or tension surrounding deeply personal issues. It is connected to feelings of hopelessness, inadequacy and self-rejection.
