ALICE A. BAILEY: Cosmic Fire, page
880 – 81: “Knowledge is the right apprehension of the laws of energy, of the conservation of force, of the sources of energy, of its qualities, its types and its vibrations. It involves an apprehension of:
- The different key vibrations.
- The centres whereby force enters.
- The channels along which it circulates.
- The triangles and other geometrical figures which it produces during evolution.
- The cycles and the ebb and flow of energy in connection with the different types of planetary manifestation, including all the kingdoms of nature.
- The true significance of those force aspects which we call “periods of pralaya” and those we call “periods of manifestation.”
