The book provides the readers with a practical understanding of these two nodes so that they can be placed in perspective. Astronomically (as per Hindu Astrology), Rahu and Ketu denote the two points of intersection of the paths of the Sun and the Moon as they move around the celestial sphere.
The fact that eclipses occur when Sun and Moon are at one of these points gives rise to the myth of the swallowing of the Sun. Therefore, Rahu and Ketu are respectively called the north and the south lunar nodes. Rahu and Ketu is considered as two strong planets. Since Rahu and Ketu are believed to have a strong impact on our lives, they are denoted as mathematical points while making calculations in Vedic Astrology.
This book attempts to dispel the darkness that surrounds Rahu and Ketu, the two nodal points of the Moon so that they can be better understood and their importance in Vedic astrology appreciated.
