The highest healing practice in Kôngo traditional society has always involved the purification of being and/or the use of spirits. This approach has been so far frowned at as having no scientific foothold, i.e., as being a mere superstition. In this paper, the author demonstrates the scientific anthropological bases of the purification of being, exposes the scientific validity of the existence of spirits, and evidences the main two approaches of the use of the spirits in divine healing as being the use of water, of herbal and mineral agents as well as the sole use of prayer. The methodology used in this paper is based on the use of the facto-deductive scheme to formulate the kemetic cosmological argument and the pre-suppositional use of the systematic natural theology thus stated to prove the scientific nature and validity of the various aspects of the Kôngo culture. The demonstration thus made has been shown to be susceptible of generalization mutatis mutandis to cover any African traditional society. Finally the author gives a glimpse of the modern continuation of African traditional spiritual healing practice.
