"The Invocation has been sent out by the combined Ashrams of the Masters and by the entire Hierarchy; it is used by its Members with constancy, exactitude and power. It will serve to integrate the two great centres: the Hierarchy and Humanity, and to relate them both in a new and dynamic manner to the "centre where the Will of God is known"."
