To mingle “with all men in a spirit of utmost kindliness and love”

Illumine and hallow your hearts; let them not be profaned by the thorns of hate or the thistles of malice. Ye dwell in one world, and have been created through the operation of one Will. Blessed is he who mingleth with all men in a spirit of utmost kindliness and love. 

- Baha’u’llah  (‘Gleanings from the Writings of Bahá'u'lláh’)
