Moreover this Matter touches the Nature of Truth. For although to thee in thy True Self, absolute and without Conditions, all this Universe, which is relative and conditioned, is an Illusion; yet to that Part of Thee by which thou perceivest it, the Law of its Being (or By-coming) is a Law of Truth. Learn then that all Relations are true upon their own Plane, and that it would be a Violation of Nature to adjust them skewwise. Thus, albeit thou hast found Thy Self, and knowest Thy Self immortal and immutable beyond Time and Space, free of Causality, so thoroughly that even thy Mind partaketh constantly thereof, thou hast in no wise altered the Relations of thy Body with its Syndromics in the World whereof it is a Part. Wouldst thou lengthen the Life of thy Body? Then accommodate thou the Conditions of thy Body to its Environment by giving it Light, Air, Food, and Exercise as its Nature requireth. So also, mutatis mutandis, do thou cherish the Health of thy Mind.
