The ancient classical texts are the foundation of which emanates the fountain of Astrological principles. 'Bhavarth Ratnakar' is one of the classical texts of Hindu Astrology on which rests the edifice of Hindu Astrology as a whole. The modern astrological world took the material from these monumental works and advanced on research to find out the veracity of the rules mentioned therein. Whether it is 'Brihat Parasara Hora Shashtra', 'Jataktatvam', 'Bhavarth Ratnaker', 'Phaldeepika' or any other texts have given us a path. The path on which scholars are expected to tread to discover the light of truth. The Astrology as a whole has been misunderstood by astrologers. It has been considered as a means of future telling. It is very narrow view of this grand subject. In fact, it is the study of Time. The word like 'Kalpurusha' and 'Hora' simply mean Time and nothing else. Therefore, reverend sage Maharishi Parashar had pronounced his work as 'Hora Shashtra' i.e. Literature of Time. All classical texts as well as modern works on Astrology are the delineations of Time in respect of human beings. The present book entitled 'Bhavarth Ratnakar' has been commented and elucidated keeping in mind the basic principle i.e. Time. The slokas of reverend sage Ramanujacharya have been commented in the light of ongoing research in the field of Astrology. The readers shall be amused with research oriented commentary and elucidation and shall be contended with the contents of the book.
