The Writings of D. B. Sleeth, Ph.D. — The basic premise of integral therapy is this: love is the healing principle. All therapeutic orientations, whether explicitly acknowledging the relationship or not, are based on this principle. Further, the efficacy of all therapeutic orientations result from a particular clinical equation: the more the awareness, the more the love. As a result, positive outcomes from all ap- proaches to clinical practice rely essentially on mindfulness, which derives from nondualism — and especially “Radical” Non-Dualism.
