The most ancient scripture giving the very fundamental principles of vedic astrology as expounded by Maharishi Parasara : versatile,and yet compact to comprehend.It touches upon the very basic as well as complexed dimensions of astrology.Also deals with every perceptible event,subject and attribute.It is for these special features that it is reckoned as the fountain head of vedic astrology. Vedic Astrology exists at three levels as statement of Gods, Sages or learned Astrologers. The text represents only the statement of Sage Parasara who stands out in the lineage of eighteen Indian sages, but is the only complete system of Vedic Astrology which covers the whole gamut of axiom which can be usefully employed to interpret future of life. Author's two decades of practical experience has been the basis to explain specific fundamentals principles to be used synergistically to interpret horoscopes. Special emphasis has been laid to highlight the understanding of Dasa system along with harmonic charts and Avasthas of planets.

Vedic Astrology like any other branch of Vedic knowledge aimed at enhancing human welfare by ameliorating sufferings. With this grand mission, sage Parasara (one of those grand eighteen sages like Narada, Vashishta, Jaimini etc.) authored this encyclopeadia text in the principles of Vedic Astrology designated as Brihat Parasara Hora Shastra (BPHS in brief). As the name connotes the text comprises of basic principles of Vedic Astrology in a comprehensive way. It essentially deals with delineation of life from conception to death; the cardinal underlying principles being those celestial condition (planetary position and pattern/combination) at birth influence to determine the pattern of whole life of human beings.

In this backdrop profound use has been made of all astrological clues lying scattered in various mythological and allied scriptures including yoga tantra etc., besides all the published material on the subject. Texture difference have been pointed out and appropriate text accepted. Hence efforts have been made to make this publication the most comprehensive as all available text has been included so as to preclude any additional consultation. A detailed glossary of these texts shall be presented at the end of the second & concluding part of the book.

Astrology is like any other science, however its practice would always remain an art as the parameters of man environments and times lead to different interpretation in different parts of the world. I say so on basis of my experience/practice through two decades over which principles laid down in BPHS progressively became lucid and amazingly true. A lot more is yet to be done especially in the face of the fact that past deeds and predestination have a definite role to play. Hence it is only through the study of Vedic Astrology that the secret of fate and freewill can be deciphered on a logical plane.
