For every era hath a spirit; the spirit of this illumined era lieth in the teachings of Bahá'u'lláh. For these lay the foundation of the oneness of the world of humanity and promulgate universal brotherhood. They are founded upon the unity of science and religion and upon investigation of truth. They uphold the principle that religion must be the cause of amity, union and harmony among men. They establish the equality of both sexes and propound economic principles which are for the happiness of individuals. They diffuse universal education, that every soul may as much as possible have a share of knowledge. They abrogate and nullify religious, racial, political, patriotic and economic prejudices and the like. Those teachings that are scattered throughout the Epistles and Tablets are the cause of the illumination and the life of the world of humanity.
