“We speak one word, and by it we intend one and seventy meanings; each one of these meanings we can explain.”

"It is evident unto thee that the Birds of Heaven and Doves of Eternity speak a twofold language. One language, the outward language, is devoid of allusions, is unconcealed and unveiled; that it may be a guiding lamp and a beaconing light whereby wayfarers may attain the heights of holiness, and seekers may advance into the realm of eternal reunion. Such are the unveiled traditions and the evident verses already mentioned. The other language is veiled and concealed, so that whatever lieth hidden in the heart of the malevolent may be made manifest and their innermost being be disclosed. Thus hath Ṣádiq, son of Muḥammad, spoken: “God verily will test them and sift them.” This is the divine standard, this is the Touchstone of God, wherewith He proveth His servants. None apprehendeth the meaning of these utterances except them whose hearts are assured, whose souls have found favour with God, and whose minds are detached from all else but Him. In such utterances, the literal meaning, as generally understood by the people, is not what hath been intended. Thus it is recorded: “Every knowledge hath seventy meanings, of which one only is known amongst the people. And when the Qá’im shall arise, He shall reveal unto men all that which remaineth.” He also saith: “We speak one word, and by it we intend one and seventy meanings; each one of these meanings we can explain.”

These things We mention only that the people may not be dismayed because of certain traditions and utterances, which have not yet been literally fulfilled, that they may rather attribute their perplexity to their own lack of understanding, and not to the non-fulfilment of the promises in the traditions, inasmuch as the meaning intended by the Imáms of the Faith is not known by this people, as evidenced by the traditions themselves. The people, therefore, must not allow such utterances to deprive them of the divine bounties, but should rather seek enlightenment from them who are the recognized Expounders thereof, so that the hidden mysteries may be unravelled, and be made manifest unto them."
