"During the last quarter of every hundred years an attempt is made by those Masters, of whom I have spoken, to help on the spiritual progress of Humanity. Towards the close of each century you will invariably find that an outpouring or upheaval of spirituality--or call it mysticism if you prefer--has taken place. Some one or more persons have appeared in the world as their agents, and a greater or less amount of occult knowledge or teaching has been given out."
