Planetary combinations (eg, unions) are known as Yogas, so this is a book of 300 yogas & essential for serious Vedic reading. For example, the Dehapushti Yoga (109) is the lord of the lagna in a movable sign aspected by a benefic & indicates a well-developed body, wealth & enjoyable life. The only difficulty is to find things in this book: Raman himself says there is no order to it, though it would appear Raman has organized by related yogas, when possible. To learn, read & memorize!
This book is intended to provide knowledge of the Yogas which indicate specific horoscopic trends. All planetary combinations are divided into two groups, viz., Yogas and Aristhas or fortunes and misfortunes. It deals with various standing combinations of yogas. The systematised account of all the important yogas is brought out so that it may illustrate practical horoscopes.
About the Author:
B.V. Raman, 1912 - 1998, did the thankless work of promoting Hindu Astrology (his term, by the way) in India since the 1940's and in the west from the 1960's onward. He remains the most renown modern Vedic astrologer. Upon his passing, ownership of his books was divided among his various children. So far, some have done a better job of keeping his books in print than others.
