The meditative faculty is akin to the mirror; if you put it before earthly objects it will reflect them. Therefore if the spirit of man is contemplating earthly subjects he will be informed of these. But if you turn the mirror of your spirits heavenwards, the heavenly constellations and the rays of the Sun of Reality will be reflected in your hearts, and the virtues of the Kingdom will be obtained.
—‘Abdu’l-Bahá, Paris Talks
