"Thou art even as a finely tempered sword concealed in the darkness of its sheath ..."

"O MY SERVANT! Thou art even as a finely tempered sword concealed in the darkness of its sheath and its value hidden from the artificer’s knowledge. Wherefore come forth from the sheath of self and desire that thy worth may be made resplendent and manifest unto all the world."

-Bahá'u'lláh, The Hidden Words of Bahá’u’lláh, No. 72 Persian
