And now concerning this wondrous and most exalted Cause. Know thou verily that many an astronomer hath announced the appearance of its star in the visible heaven. Likewise, there appeared on earth Aḥmad and Kázim,(51) those twin resplendent lights—may God sanctify their resting-place! From all that We have stated it hath become clear and manifest that before the revelation of each of the Mirrors reflecting the divine Essence, the signs heralding their advent must needs be revealed in the visible heaven as well as in the invisible, wherein is the seat of the sun of knowledge, of the moon of wisdom, and of the stars of understanding and utterance. The sign of the invisible heaven must needs be revealed in the person of that perfect man who, before each Manifestation appeareth, educateth, and prepareth the souls of men for the advent of the divine Luminary, the Light of the unity of God amongst men. And now, with reference to His words: “And then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.” These words signify that in those days men will lament the loss of the Sun of the divine beauty, of the Moon of knowledge, and of the Stars of divine wisdom. Thereupon, they will behold the countenance of the promised One, the adored Beauty, descending from heaven and riding upon the clouds. By this is meant that the divine Beauty will be made manifest from the heaven of the will of God, and will appear in the form of the human temple. The term “heaven” denoteth loftiness and exaltation, inasmuch as it is the seat of the revelation of those Manifestations of Holiness, the Day-springs of ancient glory. These ancient Beings, though delivered from the womb of their mother, have in reality descended from the heaven of the will of God. Though they be dwelling on this earth, yet their true habitations are the retreats of glory in the realms above. Whilst walking amongst mortals, they soar in the heaven of the divine presence. Without feet they tread the path of the spirit, and without wings they rise unto the exalted heights of divine unity. With every fleeting breath they cover the immensity of space, and at every moment traverse the kingdoms of the visible and the invisible. Upon their thrones is written: “Nothing whatsoever keepeth Him from being occupied with any other thing;” and on their seats is inscribed: “Verily, His ways differ every day.”(52) They are sent forth through the transcendent power of the Ancient of Days, and are raised up by the exalted will of God, the most mighty King. This is what is meant by the words: “coming in the clouds of heaven.”
