O ye Sons of Intelligence! The thin eyelid prevents the eye
from seeing the world and what is contained therein. Then think of the result
when the curtain of greed covers the sight of the heart. Say, O People! The
darkness of greed and envy obscures the light of the soul as the cloud prevents
the penetration of the sun's rays. Should one listen with the ear of
intelligence to this Utterance, he shall spread the wings of freedom and soar
with great joy toward the heaven of understanding.
- Baha’u’llah (From a Tablet; Star of the West, vol. 1, no.
1, March 21, 1910)
