This book deals with the study of astronomical science comprising five illuminating lectures : (1) The Constellations of the Zodiac, (2) The Sun and the Solar Forces, (3) The Planets and the Planetary Influence, (4) The Earth and its Relation to the Sun, (5) Heliocentric Science.
Anything that is secret and mysterious in these systems of yoga should be at once rejected. The best guide in life is strength. In religion, as in all other matters, discard everything that weakens you, have nothing to do with it.
-Swami Vivekananda
