931. This can be represented no otherwise than by the sphere of the effluvia from the body. This sphere is such that when anything impinges upon it, it either reflects it, or bends it, in accordance with its own genius or nature; wherefore, these spirits do not know that they are such and that they produce such an effect. All spirits are as it were encompassed by such a sphere, as, for instance, those who terrify and inspire fear and the like. Within that sphere nothing is admitted that is repugnant or contrary, unless it be a sphere acting more powerfully; then it is done with suffering, because the spirit and his sphere make a one. Cognitions, however, which do not flow in with cupidity, can enter and be received. 1748, Feb. 22.
