That seeker must at all times put his trust in God, must renounce the peoples of the earth, detach himself from the world of dust, and cleave unto Him Who is the Lord of Lords. He must never seek to exalt himself above any one, must wash away from the tablet of his heart every trace of pride and vainglory, must cling unto patience and resignation, observe silence, and refrain from idle talk. For the tongue is a smouldering fire, and excess of speech a deadly poison. Material fire consumeth the body, whereas the fire of the tongue devoureth both heart and soul. The force of the former lasteth but for a time, whilst the effects of the latter endure a century. (Baha'u'llah, The Kitab-i-Iqan)
