Baba Metu  delves into a system of understanding human behavior and the cosmos through dualistic principles and cyclical patterns. It begins by illustrating how ideas are generated and multiplied, drawing parallels to creation stories and biological processes like mitosis. The core concept introduced is the duality of “moist” and “dry” to describe varying degrees of sensitivity to the environment in individuals, further expanded with the hot/cold duality representing extroverted and introverted tendencies. These combinations form four elemental temperaments (cold/moist, hot/moist, hot/dry, cold/dry) that are presented as fundamental energies manifesting in all aspects of life, from human personalities to food and even cosmological concepts represented by figures like Nut and Geb in ancient Kemetic cosmology. Baba Metu  aims to provide a framework for recognizing and understanding these temperaments in oneself and others, suggesting their influence on behavior, professions, and interactions with the world.
