The Word is the master key for the whole world, inasmuch as through its potency the doors of the hearts of men, which in reality are the doors of heaven, are unlocked.
Bahá'u'lláhThe utterance of God is a lamp, whose light is these words: Ye are the fruits of one tree, and the leaves of one branch. Deal ye one with another with the utmost love and harmony... So powerful is the light of unity that it can illuminate the whole earth.
Bahá'u'lláhBeautify your tongues, O people, with truthfulness, and adorn your souls with the ornament of honesty. Beware, O people, that ye deal not treacherously with any one.
Bahá'u'lláh
