Brihat Jataka (and its commentary) are highly revered in South India. Though brief, Varahamihira's Brihat Jataka is a very intriguing book packed with ideas. Even bright people may find it difficult to read the text, but with the help of Bhattotpala's and others' commentary, it is feasible to grasp it.
Since there are a lot of commentators in this book, some of which are quite old, we can have justifiable confidence and trust in the genuineness of the current form of Brhat Jataka. These annotations retain the text and its framework in a way that would be difficult to achieve without them.
Kalyanraman says:
"The Brhat Jataka is said to contain around twenty commentators in Sanskrit alone, including Mudrakshari, Subhodhini, Sripatiyam, and Bhatttopalavritti, in addition to those in other languages. Talakkulathur Govindam Bhattathiri's Dasadhyayi is one of these Sanskrit commentaries. Vivaranam of Rudra is maybe the next notable one." (p. 203) (Kalyanraman, 2007).
There are about 407 Shlokas in the Brihat Jataka. The first section of the book delves into technical vocabulary and ideas. The second discusses the planets' properties, placements, relationships, metals, attributes, locations, and natures. The births of birds, animals, insects, and trees are discussed in the third chapter. This is deserving of a thorough examination and extensive investigation.
The fourth chapter, which is about Nisheka, discusses women's conception and other aspects. The next two chapters deal with birth anomalies and Balarishta. Amsa and Pinda Ayurdayas are explained in the seventh and eighth chapters. In determining lifespan, these are more reliable than the widely used dasa techniques. A brief narrative of Ashtakavarga is given in the ninth chapter. The profession is the focus of the eleventh. The effects of planet conjunctures are discussed in Chapter 14. Renunciation is the subject of the next chapter.
In the next five chapters, the effects of constellations, lunar effects in various signs, results of planets in various signs, effects of planetary aspects, and effects of planets in various Bhavas (houses) are discussed. The twenty-first chapter has several unique combinations. Miscellaneous things are addressed in the next chapter. Misfortune is the subject of the 23rd chapter. Female Horoscopy is the subject of the 24th Chapter, which is treated in detail in Saravali. Death is discussed in the 25th chapter. In Chapter 26, you'll learn how to revive lost or unknown horoscopes. Decanates are discussed on the 27th. The final one numbers the text's contents.
