N submitting this third volume of the series begun with Special Teachings from the Arcane Science, the author is aware that the times are not yet ready for much of its contents. Still the rapidly widening outlook of multitudes encourages the venture, and gives promise that, ere the coming of a great event — one for which in humble way this book is a preparation — certain of its chapters will be accepted, and even assimi lated, by those whose eyes are toward the New Age now almost with us, and whose hearts are preparing for that large and complete message of which these pages contain only hints and fragments. Should our explanations leave many matters more or less dark, it is because we ourselves have not yet come into the day, or else that the full light of explanation must await the word of mouth from the World Teacher himself. From the title of the preceding volume, The Heart of Things, it might be inferred that in its probings and soundings we thought to' reach the central mysteries; but, like the human heart, the heart of things is seven-fold. So, despite our previous attempt, and notwithstanding our present effort, the deepest deep remains unknown.
