It is not in our power, nor in our wish, to produce the original form, nor yet the spirit, of a production which is better lost to the world: because it was the expression of a human intellect originally greatly gifted and capable of high things, but gone utterly astray, partly by its own subtlety, partly by yielding to the temptations of the lower part of its nature, by yielding the spiritual to a keen sagacity of lower things, until it was quite fallen; and yet fallen in such a way, that it seemed not only to itself, but to mankind, not fallen at all, but wise and good, and fulfilling all the ends of intellect in such a life as ours, and proving, moreover, that earthly life was good, and all that the development of our nature demanded. All this is better forgotten; better burnt; better never thought over again; and all the more, because its aspect was so wise, and even praiseworthy. But what we must preserve of it were certain rules of life and moral diet, not exactly expressed in the document, but which, as it were, on its being duly received into Septimius's mind, were precipitated from the rich solution, and crystallized into diamonds, and which he found to be the moral dietetics, so to speak, by observing which he was to achieve the end of earthly immortality, whose physical nostrum was given in the recipe which, with the help of Doctor Portsoaken and his Aunt Keziah, he had already pretty satisfactorily made out. "Keep thy heart at seventy throbs in a minute; all more than that wears away life too quickly. If thy respiration be too quick, think with thyself that thou hast sinned against natural order and moderation. "Drink not wine nor strong drink; and observe that this rule is worthiest in its symbolic meaning. "Bask daily in the sunshine and let it rest on thy heart. "Run not; leap not; walk at a steady pace, and count thy paces per day. "If thou feelest, at any time, a throb of the heart, pause on the instant, and analyze it; fix thy mental eye steadfastly upon it, and inquire why such commotion is. "Hate not any man nor woman; be not angry, unless at any time thy blood seem a little cold and torpid; cut out all rankling feelings, they are poisonous to thee. If, in thy waking moments, or in thy dreams, thou hast thoughts of strife or unpleasantness with any man, strive quietly with thyself to forget him. "Have no friendships with an imperfect man, with a man in bad health, of violent passions, of any characteristic that evidently disturbs his own life, and so may have disturbing influence on thine. Shake not any man by the hand, because thereby, if there be any evil in the man, it is likely to be communicated to thee.
