"O friend, the heart is the dwelling of eternal mysteries, make it not the home of fleeting fancies; waste not the treasure of thy precious life in employment with this swiftly passing world. Thou comest from the world of holiness—bind not thine heart to the earth; thou art a dweller in the court of nearness—choose not the homeland of the dust."

-Bahá'u'lláh, The Seven Valleys, p. 35, The Valley of Wonderment
