Astrology is divided into three branches: Samhita, Tantra, and Hora. The Hora Wing is the Eternal Sea, which is one of them. Many texts on Jataka-Tajik-Muhurta-Prashna-Panchangnirmanastha Jataka can be found in this collection. Predictive Astrology is one of the most significant of them. This remark, "Jyotish Shastra is the ocean of prediction," is not exaggerated.
Varahamihira and other Acharyas wrote their books with this goal in mind. It is extremely difficult to cross the sea with only muscular strength, necessitating the use of ships. As a consequence, ships are constructed. Similarly, to bridge the predicted ocean, the Acharyas have created several predictive writings. The Brihat Jatak has a strong presence in these writings. As Varah Ji has stated,
होरातन्त्रमहार्णवप्रतरणे भग्नोद्यमानामहं स्वल्पं वृत्तविचित्रमर्थबहुलं शास्त्रप्लवं प्रारभे ॥ श्लो० २ ॥
This book is concise, comprehensive, and all-encompassing.
