The Garden of Alla explores the Spiritual Key to Isaiah XXXV. "Even those who love the Bible most are apt to make the mistake of looking upon it as merely a book, the greatest book ever written, no doubt, but still a book; whereas the truth about the Bible is that it is really a spiritual vortex in which spiritual power pours from the Absolute or Divine Plane into the physical plane or plane of manifestation. But the Bible is not only the great source of spiritual truth, it is also the greatest collection of literary masterpieces that we possess. Almost every literary form is represented in the Bible, both in prose and poetry. Above all, the Bible abounds in beautiful and powerful prayers and treatments, and this reason alone makes it for us the most important book in the world."- Emmet Fox
