Khat or Khet is an Egyptian word signifying the physical body, which is the seat of the Ba (Persona). The Khat, or physical body houses the Ab (heart, emotions, Waters) and the Ka (desire, passions, Fires) which communicate to the Khu (Spirit) via the Sa (Subtle Body) which surrounds the Ba (Persona). Using the Principles of Natura which govern the secret workings of the Khat, Heka may physically manifest in the body. See also Membra Animae.
