This Book titled “Marriage Compatibility in Hindu Astrology” gives a detailed and neo interpretation, extents and limits it can be used to match the horoscopes of prospect marriage couples. This book shows that Kalapurusha was used as reference in formulating the compatibilities laws in ancient Hindu Astrology. I have given the respective reasons why those ancient laws have given and their hypes have been clarified. The two groups of planets such as Mercury, Venus and Saturn form antagonists to other groups of planets such as Mars, Sun, Moon and Jupiter. These makes an important role in deciding the compatibility between couples based on moon’s star. The compatibility between Rasi lord and star lord were given in explaining vision of ancient sages in Rajju compatibility. Similarly I have given explanation for both compatibility as well as incompatibility results and their effects on potential marriage couples. I also included a chapter on Astrological hypes which are cropped up over a period of huge time line. A separate chapter also discusses the fate and free choices in selecting one’s life partner in marriage as per one’s Horoscope chart. I hope this book will be highly useful for potential marriage couples and also for amateur Astrologers and other researchers. I also authored a book titled “Unique Method of Predictions using Vimshottari Dasa System”. So the current book is just an auxiliary of it.
