I am an entity like that which you yourself become in the freedom of dreamless sleep. I am your brother of light, and have floated with you in the effulgent valleys. It is not permitted me to tell your waking earth-self of your real self, but we are all roamers of vast spaces and travellers in many ages. Next year I may be dwelling in the dark Egypt which you call ancient, or in the cruel empire of Tsan-Chan which is to come three thousand years hence. You and I have drifted to the worlds that reel about the red Arcturus, and dwelt in the bodies of the insect-philosophers that crawl proudly over the fourth moon of Jupiter. How little does the earth-self know of life and its extent! How little, indeed, ought it to know for its own tranquillity!
