O people of Bahá! The source of crafts, sciences and arts is the power of reflection. Make ye every effort that out of this ideal mine there may gleam forth such pearls of wisdom and utterance as will promote the well-being and harmony of all the kindreds of the earth.
 Under all conditions, whether in adversity or at ease, whether honored or afflicted, this Wronged One hath directed all men to show forth love, affection, compassion and harmony. And yet whenever there was any slight evidence of progress and advancement, those concealed behind the veils would sally forth and utter calumnies more wounding than the sword. They cling unto misleading and reprehensible words and suffer themselves to be deprived of the ocean of verses revealed by God. 

Bahá’u’lláh
