O peoples of the world!... 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.
- Bahá'u'lláh ('Tablets of Baha'u'lláh revealed after the Kitáb-i-Aqdas')
