“Recite ye the verses of God every morn and eventide.” (Bahá’u’lláh, ‘The Kitáb-i-Aqdas’)

August 19

O My brother! When a true seeker determineth to take the step of search in the path leading unto the knowledge of the Ancient of Days he must… at all times, put his trust in God, must renounce the peoples of the earth, must 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 vain-glory, must cling unto patience and resignation, observe silence and refrain from idle talk. For the tongue is a smoldering 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 endureth a century. 
- Baha’u’llah  (‘Gleanings from the Writings of Baha’u’llah’)
