The most important thing is to polish the mirrors of hearts
in order that they may become illumined and receptive of the divine light.
- ‘Abdu’l-Baha (From a talk, New York, 14 April 1912; ‘The Promulgation of
Universal Peace: Talks Delivered by 'Abdu'l-Bahá during His Visit to the United
States and Canada in 1912’)
