48a: "Ring-pass-not.  The circumference of the sphere of influence of any centre of positive life.  This includes the fire sphere of magnetic work of the solar orb, viewing it as the body of manifestation of a solar Logos and inclusive of an entire solar system.  This term is also applied to the sphere of activity of a planetary Logos or to a planetary scheme and could equally well be applied to the sphere of activity of the human Ego."—S. D., I, 346.
