This wealth of waters might but seem to draw From yon dark cave, but, son, the source is higher, Yon summit half-a-league in air--and higher, The cloud that hides it--higher still, the heavens Whereby the cloud was moulded, and whereout The cloud descended. Force is from the heights. "_Force is from the heights_" is the thought which underlies the Sage's interpretation of all that perplexes the younger man. We cannot fully understand what is beyond and above us, but if we are wise we shall steadily look upwards, and enough light will eventually be gained for our guidance. "Lucerna pedibus meis verbum tuum." As God's law is enough to guide our footsteps, though we cannot hope to understand His full counsel, so the light by which the spiritual world is disclosed is sufficient for those who look for it, though its disclosure is only gradual and partial. If we are said not to know what we cannot submit in its entirety to scientific tests, we can never know anything worth knowing. If, again, we are to disbelieve in the spiritual world because it is filled with mystery, what are we to say of the mysteries which face us in this earth--inexplicable yet undeniable? The conception of God is not more mysterious than the thought that a grain of sand may be divided a million times, and yet be no nearer its ultimate division than it is now. Time and space are full of mystery. A man under chloroform has been known to pass many hours of sensation in a few minutes. Time is made an objective measure of things, and yet its phenomena are so subjective that Kant conceived it to have no real existence. When the younger man complains that "the Nameless Power or Powers that rule were never heard nor seen," the Sage thus replies: If thou would'st hear the Nameless, and wilt dive Into the Temple-cave of thine own self, There, brooding by the central altar, thou May'st haply learn the Nameless hath a voice, By which thou wilt abide, if thou be wise, As if thou knewest, tho' thou canst not know; For Knowledge is the swallow on the lake That sees and stirs the surface-shadow there But never yet hath dipt into the abysm, The Abysm of all Abysms, beneath, within The blue of sky and sea, the green of earth, And in the million-millionth of a grain, Which cleft and cleft again for evermore, And ever vanishing, never vanishes, To me, my son, more mystic than myself, Or even than the Nameless is to me.
