It seems to me absolutely true, that our world, which appears to us the surface of all things, is really the bottom of a deep ocean: all our trees are submarine growths, and we are weird, scaly-clad submarine fauna, feeding ourselves on offal like shrimps. Only occasionally the soul rises gasping through the fathomless fathoms under which we live, far up to the surface of the ether, where there is true air.
The jungle which is presided over by Kudu, the sun, is a very different jungle from that of Goro, the moon. The diurnal jungle has its own aspect--its own lights and shades, its own birds, its own blooms, its own beasts ... The lights and shades of the nocturnal jungle are as different as one might imagine the lights and shades of another world to differ from those of our world.
