Ascribe not to any soul that which thou wouldst not have ascribed to thee, and say not that which though doest not.
Bahá'u'lláhSpeak no evil, that thou mayest not hear it spoken unto thee, and magnify not the faults of others that thine own faults may not appear great.
Bahá'u'lláhA kindly tongue is the lodestone of the hearts of men. It is the bread of the spirit, it clotheth the words with meaning, it is the fountain of the light of wisdom and understanding...
