Short answer: In Jainism, there is no core link between astrology and spiritual practice. The tradition emphasizes karma, right conduct, self-d discipline, and non-violence, rather than predestination or fate read from the stars.

Key points:

• Karma over fate: Jainism teaches that one’s future results come from one’s own actions, thoughts, and intentions, not from astrological charts.
• Suttas and Jain ethics: The canonical Jain texts focus on ahimsa (non-harm), satya (truth), asteya (non-stealing), brahmacharya (celibacy), and aparigraha (non-attachment). They do not make astrology a central or authoritative tool for spiritual progress.
• Differences between Digambara and Śvetāmbara: There isn’t a canonical, uniform endorsement of astrology in either tradition. Some local practices or folk beliefs may incorporate astrology, but they are not essential to Jain doctrine.
• Practical view: Many Jains regard astrology as unreliable for making moral or spiritual decisions; emphasis stays on personal discipline, ethical living, and the choice to shed karmic bondage.
