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.
(Baha'u'llah, ‘The Kitab-i-Iqan’)
