Many ideas rise up in the human mind; some of them concern
truth and some untruth. Among such ideas those which owe their source to the Light
of Truth will be realized in the outward world; while others of a different
origin vanish, come and go like waves on the sea of imagination and find no
realization in the world of existence.

vol. 2')
