The Luminous Call

"In the treasuries of the knowledge of God there lieth concealed a knowledge which, when applied, will largely, though not wholly, eliminate fear. This knowledge, however, should be taught from childhood, as it will greatly aid in its elimination. Whatever decreaseth fear increaseth courage. Should the Will of God assist Us, there would flow out from the Pen of the Divine Expounder a lengthy exposition of that which hath been mentioned, and there would be revealed, in the field of arts and sciences, what would renew the world and the nations. A word hath, likewise, been written down and recorded by the Pen of the Most High in the Crimson Book which is capable of fully disclosing that force which is hid in men, nay of redoubling its potency. We implore God—exalted and glorified be He—to graciously assist His servants to do that which is pleasing and acceptable unto Him."

-Bahá'u'lláh, Epistle to the Son of the Wolf, p. 32
