Our own mind is a human analogue of the Universal Mind. Thus in its character and working, Nature provides an easy lesson in divine metaphysics. If we wish to obtain some slight hint as to the nature of the highest kind of mental existence, that is, of God, we must examine the nature of our own individual mind, limited and imperfect though it be. Now philosophy is not afraid to admit pantheism but does not limit itself to pantheism. It also affirms transcendentalism but does not stop with it. It declares that the Unique Reality could never become transformed into the cosmos in the sense of losing its own uniqueness. But at the same time it declares that the cosmos is nevertheless one with and not apart from the Reality. The easiest way to grasp this is to symbolize the cosmos as human thoughts and the Reality as human mind. Our thoughts are nothing other than a form of mind, yet our mind loses nothing of itself when thoughts arise. The World-Mind is immanent in but not confined by the universe in the same way that a man's mind may be said to be immanent in but not confined by his thoughts. Furthermore, not only may we find it helpful in the effort to understand the relation which the cosmos bears to the World-Mind, to compare it with the relation which a thought bears to its thinker or his speech to a speaker, but when we consider how our own mind is able to generate thoughts of the most multivaried kind, we need not be surprised that the Universal Mind is able to generate the inexhaustibly varied host of thought-forms which constitute the cosmos.
