whether greater ability is displayed in the argumentative reasoning of the 
  Mîzan-ul-Haqq, or in the moral discussions of the  Tarîq-ul-Hyât; the latter,
  perhaps, from the abstract nature of the subject, deserve the highest praise.
  Each, indeed, has its peculiar merit, and with the  Miftâh form a whole,
  placing before the Mohammedan almost every point which he is at present
  prepared for. To be interested or profited by the  Tarîq-ul-Hyât, requires, no
  doubt, a state of mind much in advance of that which the ordinary Moslem now
  possesses, for the subject of inward corruption is one foreign to his ideas;
  but the day is, we trust, approaching, when this will no longer be the case;
  when the leaven of that knowledge which is even now pervading the country
  will work a mighty change in their feelings and ideas; and then, by the
  blessing of God, will the heart respond with notes of conviction and
  repentance to the touches of truth contained in this volume. Pfander has
  indeed conferred in these books an inestimable boon upon this country; and we
  are much mistaken if they do not assume the place of standard treatises among
  such as interest themselves in this great question, and especially among our
  native Christians; for though primarily adapted to the professors of Islam,
  their contents must always possess a general interest.
