Book excerpt: This book is an attempt to create awareness about true nature of a number of important Yogas mentioned in Vedic astrology. These Yogas include benefic Yogas like Hamsa Yoga, Malavya Yoga, Ruchaka Yoga and Vipreet Rajyoga; and they include malefic Yogas like Guru Chandal Yoga, Grahan Yoga and Angarak Yoga. This edition features comprehensive details about various yogas. The focus here is going deeper and deeper. In case of each one of these Yogas, its prevalent definition is given first. The scientific as well as logical probabilities of that definition holding well or not are discussed after that. Then the additional conditions required for proper formation of the Yoga are considered. Finally, other important factors which may affect the good or bad results given by that particular Yoga are discussed. These factors include placements of various planets in various houses, signs, nakshatras and navamshas; influences of other benefic and malefic planets; and the impact of planetary periods. This way, a logical, balanced and comprehensive approach has been implemented in case of each one of these Yogas.
