O people! Words must be supported by deeds, for deeds are the true test of words. Without the former, the latter can never quench the thirst of the yearning soul, nor unlock the portals of vision before the eyes of the blind. The Lord of celestial wisdom saith: A harsh word is even as a sword thrust; a gentle word as milk. The latter leadeth the children of men unto knowledge and conferreth upon them true distinction.
- Baha’u’llah (‘The Tabernacle of Unity, Bahá’u’lláh’s Responses to Mánikchí Sáhib and Other Writings’)
