Nowhere but in the Kitáb-i-Íqán, Bahá’u’lláh’s masterly exposition of the one unifying truth underlying all the Revelations of the past, can we obtain a clearer apprehension of the potency of those forces inherent in that Preliminary Manifestation with which His own Faith stands indissolubly associated. Expatiating upon the unfathomed import of the signs and tokens that have accompanied the Revelation proclaimed by the Báb, the promised Qá’im, He recalls these prophetic words: “Knowledge is twenty and seven letters. All that the Prophets have revealed are two letters thereof. No man thus far hath known more than these two letters. But when the Qá’im shall arise, He will cause the remaining twenty and five letters to be made manifest.” “Behold,” adds Bahá’u’lláh, “how great and lofty is His station!”
