Far from knowledge being limited, Bahá’u’lláh quotes the
Muslim tradition that "every knowledge hath seventy meanings," and
asserts that the "meaning" of the Word of God "can never be
exhausted." This potential richness of meaning is underlined by the
provision whereby future Guardians, while not abrogating the
"interpretations of former Guardians," may "elaborate and
elucidate former interpretations," as set out in the extract from a letter
dated 19 February 1947 which was written on behalf of Shoghi Effendi to an
individual believer: “. . . regarding future Guardians: they cannot
"abrogate" the interpretations of former Guardians, as this would
imply not only lack of guidance but mistakes in making them; however they can
elaborate and elucidate former interpretations, and can certainly abrogate some
former ruling laid down as a temporary necessity by a former Guardian.”
