All the volumes that I have previously written belong to the formative stage. Only now, after thirty years unceasing travail and fearless exploration have I attained a satisfying fullness in my comprehension of this abstruse subject, a clear perspective of all its tangled ramifications and a joyous new revelation from a higher source hitherto known only obscurely and distantly. All my further writings will bear the impress of this change and will show by their character how imperfect are my earlier ones. Nevertheless, on certain principal matters, what I then wrote has all along remained and still remains my settled view and indeed has been thoroughly confirmed by time. Such, for instance, are (l) the soul's real existence, (2) the necessity for and the great benefits arising from meditation, (3) the supreme value of the spiritual quest, and (4) the view that loyalty to mysticism need not entail disloyalty to reason.
