Ascribe not to any soul that which thou wouldst not have ascribed to thee, and say not that which though doest not.
Bahá'u'lláhThe betterment of the world can be accomplished through pure and goodly deeds and through commendable and seemly conduct.
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.
