The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island in the midst of black seas of infinity and it was not meant that we should voyage far. Some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality that we shall either go mad from the relevation or flee from the deadly light into the peace and safety of a new dark age. Theosophists have guessed at the awesome grandeur of the cosmic cycle wherein our world and human race form transient incidents.
