Beautify your tongues, O people, with truthfulness, and adorn your souls with the ornament of honesty. Beware, O people, that ye deal not treacherously with any one.
Bahá'u'lláhThe Great Being saith: Human utterance is an essence which aspireth to exert its influence and needeth moderation. As to its influence, this is conditional upon refinement which in turn is dependent upon hearts which are detached and pure. As to its moderation, this hath to be combined with tact and wisdom as prescribed in the Holy Scriptures and Tablets.
Bahá'u'lláhBend your minds and wills to the education of the peoples and kindreds of the earth, that haply the dissensions that divide it may, through the power of the Most Great Name, be blotted out from its face, and all mankind become the upholders of one Order, and the inhabitants of one City.
