We, verily, have chosen courtesy, and made it the true mark
of such as are nigh unto Him. Courtesy is, in truth, a raiment which fitteth
all men, whether young or old. Well is it with him that adorneth his temple
therewith, and woe unto him who is deprived of this great bounty.
(Baha’u’llah,
‘Epistle to the Son of the Wolf’)
