Arts, crafts and sciences uplift the world of being, and are conducive to its exaltation. Knowledge is as wings to man's life, and a ladder for his ascent. Its acquisition is incumbent upon everyone.
Bahá'u'lláhRegard ye the world as a man's body, which is afflicted with diverse ailments, and the recovery of which dependeth upon the harmonizing of all its component elements.
Bahá'u'lláhKnow verily that the purpose underlying all these symbolic terms and abstruse allusions, which emanate from the revealers of Gods holy cause, hath been to test and prove the peoples of the world; that thereby the earth of the pure and illuminated hearts may be known from the perishable and barren soil.
