So long as the thoughts of an individual are scattered he will achieve no results, but if his thinking
be concentrated on a single point wonderful will be the fruits thereof.
One cannot obtain the full force of the sunlight when it is
cast on a flat mirror, but once the sun shineth upon a concave mirror, or on a
lens that is convex, all its heat will be concentrated on a single point, and
that one point will burn the hottest. Thus is it necessary to focus one’s
thinking on a single point so that it will become an effective force.
- ‘Abdu’l-Baha (‘Selections from the Writings of ‘Abdu’l-Baha’)
