It is clear and evident to thee that all the Prophets are
the Temples of the Cause of God, Who have appeared clothed in divers attire. If
thou wilt observe with discriminating eyes, thou wilt behold Them all abiding
in the same tabernacle, soaring in the same heaven, seated upon the same
throne, uttering the same speech, and proclaiming the same Faith. Such is the
unity of those Essences of Being, those Luminaries of infinite and immeasurable
splendor! Wherefore, should one of these Manifestations of Holiness proclaim
saying: “I am the return of all the Prophets,” He, verily, speaketh the truth.
In like manner, in every subsequent Revelation, the return of the former
Revelation is a fact, the truth of which is firmly established....
