Consider the fact that our individual lives are totally suspended during sleep, that the waves of personal consciousness then merge utterly in the ocean. How clearly this shows the Divine to be also the Infinite and Universal, our lack of true spirituality, and our possession at best of its pale reflection! For where else could we go to sleep except in this Infinite and Universal Mind? Yet we know it not! To get rid of such ignorance, to attain transcendental insight into the fourth state of being, is the most wonderful of all the tasks which this philosophy sets before us.
