Dissipate not the wealth of your precious lives in the
pursuit of evil and corrupt affection, nor let your endeavours be spent in
promoting your personal interest. Be generous in your days of plenty, and be
patient in the hour of loss. Adversity is followed by success and rejoicings
follow woe. 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)
