O My Servants! Ye are the trees of My garden; ye must give
forth goodly and wondrous fruits, that ye yourselves and others may profit
therefrom. Thus it is incumbent on every one to engage in crafts and
professions, for therein lies the secret of wealth, O men of understanding! For
results depend upon means, and the grace of God shall be all-sufficient unto
you. Trees that yield no fruit have been and will ever be for the fire.
- Baha’u’llah (‘The Hidden Words’)
