We are now in a position to say that the first necessity of the life of the Spirit is the sublimation of the instinctive life, involving the transfer of our interest and energy to new objectives, the giving of our old vigour to new longings and new loves.  It appears that the invitation of religion to a change of heart, rather than a change of belief, is founded on solid psychological laws.  I need not dwell on the way in which Divine love, as the saints have understood it, answers to the complete sublimation of our strongest natural passion; or the extent in which the highest experiences of the religious life satisfy man’s instinctive craving for self-realization within a greater Reality, how he feels himself to be fed with a mysterious food, quickened by a fresh dower of life, assured of his own safety within a friendly universe, given a new objective for his energy.  It is notorious that one of the most striking things about a truly spiritual man is, that he has achieved a certain stability which others lack.  In him, the central craving of the psyche for more life and more love has reached its bourne; instead of feeding upon those secondary objects of desire which may lull our restlessness but cannot heal it He loves the thing which he ought to love, wants to do the deeds which he ought to do, and finds all aspects of his personality satisfied in one objective.  Every one has really a forced option between the costly effort to achieve this sublimation of impulse, this unification of the self on spiritual levels, and the quiet evasion of it which is really a capitulation to the animal instincts and unordered cravings of our many-levelled being.  We cannot stand still; and this steady downward pull keeps us ever in mind of all the backward-tending possibilities collectively to be thought of as sin, and explains to us why sloth, lack of spiritual energy, is held by religion to be one of the capital forms of human wrongness.

I go on to another point, which I regard as of special importance.

It must not be supposed that the life of the Spirit begins and with the sublimation of, the instinctive and emotional life; though this is indeed for it a central necessity.  Nor must we take it for granted that the apparent redirection of impulse to spiritual objects is always and inevitably an advance.  All who are or may be concerned with the spiritual training, help, and counselling of others ought clearly to recognize that there are elements in religious experience which represent, not a true sublimation, but either disguised primitive cravings and ideas, or uprushes from lower instinctive levels:  for these experiences have their special dangers.  As we shall see when we come to their more detailed study, devotional practices tend to produce that state which psychologists call mobility of the threshold of consciousness; and may easily permit the emergence of natural inclinations and desires, of which the self does not recognize the real character.  As
