From the Preface: "The purpose of this book is to familiarize western Astrologers with the Sidereal system of using the Moon Mansions". Mohan Koparkar divides the Zodiac into 27 equal parts, based upon daily lunar movement, which he uses to get a wider spectrum of chart delineation. Key words for each mansion and all planets in the various 27 mansions are described, including Pluto & Ascendant. Chart comparison using the method of moon-mansions and other special features associated with the region of the sky are used.
