O thou who art firm in the Covenant of God!
…in this new century the attainment of science, arts and belles lettres, whether divine or worldly, material or spiritual, is a matter which is acceptable before God and a duty which is incumbent upon us to accomplish. Therefore, never deny the spiritual things to the material, rather both are incumbent upon thee. Nevertheless, at the time when thou art working for such a scientific attainment, thou must be controlled by the attraction of the love of thy Glorious Lord and mindful of mentioning His Splendid Name. This being the case, thou must attain the art thou art studying to its perfection.
