A kindly tongue is the lodestone of the hearts of men. It is the bread of the spirit, it clotheth the words with meaning, it is the fountain of the light of wisdom and understanding...
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
