The best justification which can be offered for the expression _sons_ of the universe as applied to these invisible companions is to be found in the inevitable anthropomorphism of all human thought. The breaking point, so to speak, of man's vision, that ecstasy of comprehension which I call his apex-thought, is the moment which makes him aware of these companions' existence. And, at this ecstatic moment, all individual souls find their personality deepened to such a point that they feel themselves possessed of the very secret of the ultimate duality, feel themselves to be, in fact, unfathomable personifications of that duality. And their intimation or vision with regard to the gods presents itself to them at that moment as the very nature and true being of the gods. Yet it must be remembered that this intimation is a thing which we reach only by pain and exquisite effort; is a thing, in fact, which is the culminating point of an elaborate and difficult "work of art" requiring a rhythm and a harmony in our nature attained by no easy road.
Since, therefore, the reality of these invisible companions though implied in all our intercourse with one another, is only visualized as actual and authentic when our subjective vision is at its highest point, and since when our subjective vision is at its highest point it conveys the sensation, rightly or wrongly, that what we call our "universe" is _their_ universe also, it is not without justification that we use the anthropomorphic expression "the sons of the universe" to describe these invisible companions.
This expression, the sons of the universe, this idea of an objective standard of all ideas, is something that we attain with difficulty and not something that we just pick up as we go along. The "objective," in this sense, is the supreme attainment of the "subjective." And although when we have found these companions they become real and actual, we must not forget that, in the long process of escaping from the subjectivity of ourselves into the objectivity of their existence, it was our own subjective vision with the rhythmic ecstasy of its apex-thought which led us to the brink of this discovery. Thus the expression "the sons of the universe" finds its justification. For they are the objective discovery, as well as the objective implication, of all our human and subjective visions. We and they together create the universe and together become the "children" of the world we create.
