Justice and equity are twin Guardians that watch over men. From them are revealed such blessed and perspicuous words as are the cause of the well-being of the world and the protection of the nations.
Bahá'u'lláhO Son of Spirit! My first counsel is this: Possess a pure, kindly and radiant heart, that thine may be a sovereignty ancient, imperishable and everlasting.
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.
Bahá'u'lláh
