This is the second major book about astrology written by Samael Aun Weor.
"It is really lamentable that this living human zodiac, the microcosm, sleeps so profoundly. On the basis of tremendous super-efforts, it becomes indispensable to achieve the awakening of consciousness in each of our twelve zodiacal signs.
"Light and consciousness are two phenomena of the same thing: to a lesser degree of consciousness there corresponds a lesser degree of light; to a greater degree of consciousness, a greater degree of light.
"We need to awaken consciousness in order to cause each of the twelve parts of our own microcosmic zodiac to shine and sparkle. Our entire zodiac must become light and splendor." - Samael Aun Weor
