Let each morn be better than its eve and each morrow richer than its yesterday. Man's merit lieth in service and virtue and not in the pageantry of wealth and riches ... Guard against idleness and sloth, and cling unto that which profiteth mankind, whether young or old, whether high or low. Beware lest ye sow tares of dissension among men or plant thorns of doubt in pure and radiant hearts.
(Baha'u'llah, Tablets of Baha'u'llah, p. 138)
