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.
