Brihat Jataka has over 407 Shlokas. The first in this book explains the technical terms and concepts. The second explains the characteristics, positions, relations, metals, qualities, places and natures of the planets. The third chapter deals with the births of birds, animals, insects and trees. This deserves an elaborate treatment and long research.
The fourth chapter dealing with Nisheka refers to women’s conception, and other factors. Peculiarities of birth and Balarishta are taken up in the next two chapters. The seventh and eighth chapters explain Amsa and Pinda Ayurdayas. These have greater validity than the popularly used dasa systems in determining longevity.

Influences of the constellations, lunar effects in the different signs, results of planets in various signs, effects of the planetary aspects, and effects of the planets in various Bhavas (houses) are dealt with in the next five chapters.
