If my soul could get away from this so-called prison, be granted all the list of attributes generally bestowed on spirits, my first ramble on spirit-wings would not be among the volcanoes of the moon. Nor should I follow the sunbeams to their sources in the sun. I should hover about the beauty of our own good star. I should not go moping around the tombs, nor around the artificial desolation of men. I should study Nature's laws in all their crossings and unions: I should follow magnetic streams to their source and follow the shores of our magnetic oceans. I should go among the rays of the aurora, and follow them to their beginnings, and study their dealings and communions with other powers and expressions of matter. And I should go to the very center of our globe and read the whole splendid page from the beginning.
