In Jainism, there is actually no “best book on astrology” in the religious sense.

Key points in simple words:

1. Astrology is not part of core Jain Dharma

- Jain scriptures focus on: - Ahimsa (non‑violence) - Satya (truth) - Asteya (non‑stealing) - Brahmacharya (celibacy/chastity) - Aparigraha (non‑possessiveness) - And on karma, right faith, right knowledge, right conduct. - They do not make astrology (kundli, grah‑dosh, etc.) a required or main tool for spiritual progress.

1. Digambar and Shwetambar – both

- Neither tradition has an officially accepted “Jain astrology shastra” like we have Agams, Purans, or major commentaries. - Some later Jain authors wrote jyotish‑type books, but these are cultural/traditional, not central Dharma texts. ( jainknowledge.com)

1. If you want to study as a Jain

- First priority: study Jain granths on karma, ethics, and moksha. - If you still read astrology books, keep clear in mind: - Your life is shaped mainly by your own karma and present effort, not by stars. - Never use astrology to justify violence, cheating, or breaking vows. ( jainknowledge.com)

So, from a Jain‑Dharma point of view, it is more important to read good books on karma and right conduct than to look for a “best Jain astrology book.”
