It is not correct to regard The Hidden Teaching Beyond Yoga as the continuation of The Quest of the Overself. It continues only the metaphysical part of that book. The mystical part is to some extent continued in The Wisdom of the Overself. The religious devotional and moral re-educatory parts have not yet been written about in any of my books, nor have I described the various stages and experiences of the aspirant on the Quest.
