The causal body, called sometimes (though inaccurately) the "karana sarira," has its place on the third subplane of the mental plane, the lowest abstract plane, and the one whereon the Ray of the third Logos provides the necessary "light for construction." (This is because each subplane comes specially under the influence of its Number, Name, or Lord.) When the hour strikes and the vehicles for buddhi are to be coordinated certain great Beings, Lords of the Flame, or Manasadevas, through driving external force, come in conjunction with the material of that subplane, and vitalize it with Their Own energy.

First. There appear upon the third subplane of the mental plane certain vibratory impulses¡ªnine in number¡ªcorresponding to the fivefold vibration of these Manasadevas in conjunction with the fourfold vibration set up from below and inherent in the matter of this subplane, the fifth from the lower standpoint.
