The theme of education in the Bahá’í Faith is given emphasis. The Bahá’í teachings focus on promoting a moral and spiritual education, in addition to the arts, trades, sciences and professions. The emphasis on education is a means for social and national improvement. Since all Bahá’ís have the duty to do work that is useful to humanity, Bahá’í education is meant to prepare Bahá’ís to perform such work. Bahá’u’lláh wrote: "Regard man as a mine rich in gems of inestimable value. Education can, alone, cause it to reveal its treasures, and enable mankind to benefit therefrom."
