Thou hast, moreover, asked Me concerning the nature of the celestial spheres. To comprehend their nature, it would be necessary to inquire into the meaning of the allusions that have been made in the Books of old to the celestial spheres and the heavens, and to discover the character of their relationship to this physical world, and the influence which they exert upon it. Every heart is filled with wonder at so bewildering a theme, and every mind is perplexed by its mystery. God, alone, can fathom its import. The learned men, that have fixed at several thousand years the life of this earth, have failed, throughout the long period of their observation, to consider either the number or the age of the other planets. Consider, moreover, the manifold divergencies that have resulted from the theories propounded by these men. Know thou that every fixed star hath its own planets, and every planet its own creatures, whose number no man can compute. O thou that hast fixed thine eyes upon My countenance! The Day Spring of Glory hath, in this Day, manifested its radiance, and the Voice of the Most High is calling. We have formerly uttered these words: “This is not the day for any man to question his Lord. It behoveth whosoever hath hearkened to the Call of God, as voiced by Him Who is the Day Spring of Glory, to arise and cry out: ‘Here am I, here am I, O Lord of all Names; here am I, here am I, O Maker of the heavens! I testify that, through Thy Revelation, the things hidden in the Books of God have been revealed, and that whatsoever hath been recorded by Thy Messengers in the sacred Scriptures hath been fulfilled.’” LXXXIII: CONSIDER THE RATIONAL FACULTY WITH WHICH... Consider the rational faculty with which God hath endowed the essence of man. Examine thine own self, and behold how thy motion and stillness, thy will and purpose, thy sight and hearing, thy sense of smell and power of speech, and whatever else is related to, or transcendeth, thy physical senses or spiritual perceptions, all proceed from, and owe their existence to, this same faculty. So closely are they related unto it, that if in less than the twinkling of an eye its relationship to the human body be severed, each and every one of these senses will cease immediately to exercise its function, and will be deprived of the power to manifest the evidences of its activity. It is indubitably clear and evident that each of these afore-mentioned instruments has depended, and will ever continue to depend, for its proper functioning on this rational faculty, which should be regarded as a sign of the revelation of Him Who is the sovereign Lord of all. Through its manifestation all these names and attributes have been revealed, and by the suspension of its action they are all destroyed and perish.
