Book excerpt: This volume deals with the underlying structure of occult teaching for the present era and with those vast cosmic processes reproduced through all areas of life from universe to atom. A large section of the book gives a detailed exposition of Solar Fire, the Fire of Mind, since this is the dominant energy to be understood and controlled during this second solar system. A Treatise on Cosmic Fire provides a compact outline of a scheme of cosmology, philosophy and psychology, and serves as a basic reference and text book.
