Bahá’u’lláh made the utmost efforts to educate [His people] and incite [them] to morality, the acquisition of the sciences and arts of all countries, kindly dealing with all the nations of the earth, desire for the welfare of all peoples, sociability, concord, obedience, submissiveness, instruction of [their] children, production of what is needful for the human race, and inauguration of true happiness for mankind; and He continually kept sending tracts of admonition to all parts, whereby a wonderful effect was produced.
