My Calamity is my providence, outwardly it is fire and vengeance, but inwardly it is light and mercy.
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'lláhShould the fragrance of Thy praise be shed abroad by any of the divers tongues of the world, out of the East or out of the West, it would, verily, be prized and greatly cherished.
Bahá'u'lláhAscribe not to any soul that which thou wouldst not have ascribed to thee, and say not that which though doest not.
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.
