14 THE KEY OF MYSTERIES

Most High, because, deluded by Satan, he thinks in his heart—we take refuge in God from such blasphemy—that the absolutely Wise God is not superior to him in wisdom and knowledge, and that God is unable to reveal in His holy word such matters as pass man's comprehension.

But if a man refuses to accept and believe anything that he cannot fully and completely understand, what is there in the whole universe that he will be able on these terms to believe? He will be like the ancient philosopher who thought he had attained perfect wisdom when he said, 'I know nothing, not even that I know nothing.' Whoever believes nothing that he cannot understand must necessarily deny the existence of God, because evidently God's nature and His mode of existence are beyond the limits of man's thought, understanding and imagination. Such a man must deny his own existence, too, for he has not yet understood and will never fully understand how God created him in his mother's womb, or what his spirit really is, and how it is associated with his body. On his own principles such a man must every day deny thousands of things, even though every moment they occur to his view, and though their existence is clearer than the sun, for he cannot fully comprehend their nature, their inward potencies and their outward effects.

Has any wise man ever yet discovered by investigation. how it is possible that from a small seed a great tree should grow, that thousands of seeds should be formed on it, and that in each one of them there should reside the same power as in the first seed, so that thousands of other trees should spring from it, all resembling the original tree? Who has the ability to explain how it is that, through the energy and under the influence of the same soil, air, sun and rain, various plants and different kinds of flowers, trees and fruits spring up and grow, differing from one another very much in form, colour, peculiarities and virtues? Again, who has fully explained the mystery of how it is that man's small eye can see the world at large as far as the limits of the horizon? We know how the image of exterior objects falls upon the retina and there produces a photograph, as it were, but we do not know how that picture is conveyed to the brain, unless the optic nerve acts somewhat like a telegraph wire. When the brain receives the impression of the exterior object, how does the material brain convey the picture to the immaterial ego, so that the man can truthfully say, 'I see it'? This nobody has as yet been able to explain; yet the man who, because he could not understand the process of sight, declared that he did not believe
