He knows also that the condition of other discarnate individualities is similar to his own, and that consequently each one must necessarily live in a world apart--a world of his own creation, because none of them possess the objective mentality by which to direct their subjective currents so as to make them penetrate into the sphere of another subjective entity, which is the _modus operandi_ of telepathy. Thus he is conscious of his own inability to hold intercourse with other personalities; for though he may for his own pleasure create the semblance of them in his dream-life, yet he knows that these are creations of his own mind, and that while he appears to be conversing with a friend amid the most lovely surroundings the friend himself may be having experiences of a very different description. I am, of course, speaking now of persons who have passed over in a very high state of development and with a very considerable, though still imperfect, knowledge of the Law of their own being. Probably the majority take their dream-life for an external reality; and, in any case, all who have passed over without carrying their objective mentality along with them must be shut up in their individual subjective spheres and cease to function as centers of creative power so long as they do not emerge from that state. But the highly advanced individuals of whom I am now speaking have passed over with a true knowledge of the Law of the relation between subjective and objective mind and have therefore brought with them a _subjective_ knowledge of this truth; and therefore, however otherwise in a certain sense happy, they must still be conscious of a fundamental limitation which prevents their further advance. And this consciousness can produce only one result, an ever-growing longing for the removal of this limitation--and this represents the intense desire of the Spirit, as individualized in these souls, to attain to the conditions under which it can freely exercise its creative power. Sub-consciously this is the desire of _all_ souls, for it is that continual pressing forward of the Spirit for manifestation out of which the whole Creative Process arises; and so it is that the great cry perpetually ascends to God from all as yet undelivered souls, whether in or out of the body, for the deliverance which they knowingly or unknowingly desire.
