Quaternary, Lower
From Theosopedia
In the theosophical septenary constitution of the human being, the seven are grouped into the upper triad (Atma-buddhi-manas) and a lower quaternary, consisting of the physical body, prana (vital energy), LINGA-SARIRA (the astral double), KAMA-RUPA (desire body). Later theosophical writers re-classified the lower quaternary as the physical body, etheric double, astral body (kama-rupa) and the lower mental body. This lower quaternary constitutes the mortal personality that perishes in stages after each incarnation. Only the upper triad remains which later will gather unto itself a new personality when it incarnates again.
