Occult or esoteric anatomy and physiology is also studied, which refers to the study of the supra-sensible bodies of minerals, plants, animals (rational and irrational), and human beings. It is said that everyone contains seven bodies, closely related to the Theosophical septenary, which Aun Weor calls physical, vital, emotional (astral), mental, causal, buddhic and atmic. Aun Weor differentiates between an intellectual animal and an authentic human being through the differences in the vehicles of emotion (astral body), mind (mental body) and will (causal body). Intellectual animals (ordinary man and woman) are said to contain the Lunar Astral Body, the Lunar Mental Body, and the Lunar Causal Body, each referred to by different names in different schools of Occultism. It is stated that these lunar bodies are the result of mechanical evolution through the mineral, plant and animal kingdoms and therefore, they are of an infrahuman or animal quality. The only true difference between the rational animal and irrational animals is the intellect, which gives the former the ability to become human, or as Aun Weor states, the intellectual animal has the "seed" or potential of a human latently existing within its sexual organs.
