O Son of Dust! The wise are they that speak not unless they
obtain a hearing, even as the cup-bearer, who proffereth not his cup till he
findeth a seeker, and the lover who crieth not out from the depths of his heart
until he gazeth upon the beauty of his beloved. Wherefore sow the seeds of
wisdom and knowledge in the pure soil of the heart, and keep them hidden, till
the hyacinths of divine wisdom spring from the heart and not from mire and
clay.
- Baha’u’llah (‘The Hidden Words of Baha’u’llah’)
