The Great Being saith: The man of consummate learning and the sage endowed with penetrating wisdom are the two eyes to the body of mankind. God willing, the earth shall never be deprived of these two greatest gifts. (Baha’u’llah, ‘Tablets of Bahá'u'lláh Revealed after the Kitáb-i-Aqdas’; The Compilation of Compilations, vol. III, Scholarship)
