"One of the most important implications of the research of holotropic states is the realization that many of the conditions, which are currently diagnosed as psychotic and indiscriminately treated by suppressive medication, are actually difficult stages of a radical personality transformation and of spiritual opening. If they are correctly understood and supported, these psychospiritual crises can result in emotional and psychosomatic healing, remarkable psychological transformation, and consciousness evolution."
