Short answer: Jainism does not endorse astrology-based horoscopes (kundli) as a means to determine or predestine life events, including marriage. The Jain view centers on karma and spiritual effort, not on fate decided by planetary positions.

Key points:

• Karma and the soul: In Jainism, the circumstances of this life (including health, wealth, relationships) are the result of accumulated karma. The path to a better present and future is through right conduct (ahara), right faith (shraddha), and right knowledge (jnana). Past karma influences present experience, but it is not a fixed script that cannot be changed; deliberate ethical action can alter the soul’s trajectory.

• Astrology and predestination: Traditional Jain scriptures do not promote astrology or kundli as a reliable guide to life events or to marriage matching. Many Jain monks and scholars caution against interpreting celestial positions as controlling or predictive of personal outcomes.

• Marriage and compatibility: In Jain thought, the focus for a harmonious marriage should be ethical conduct, mutual respect, shared values (non-violence, truth, restraint), family support, and the ability to follow a dharmic path together. Judging a potential alliance by a “kundli match” or by notions of “manglik” is not central to Jain concerns. The spiritual aim is purification of the soul and the wellbeing of both partners’ vows and duties, not fulfilling astrological promises.

• Manglik and non-manglik: The concept of manglik (a planetary position thought to bring misfortune to marriage) belongs to certain Hindu astrological traditions. It is not a Jain doctrinal category. Jain practice does not require or prioritize matching such astrological conditions for a marriage to be valid or spiritually legitimate.

• Love and karmic factors: Genuine love and commitment can be meaningful in Jainism when backed by ethical restraint, mutual service, and commitment to a dharma-driven life. If karmic patterns suggest hardship, the Jain response is to cultivate right conduct, reduce negative karma through renunciation of harmful acts, and pursue spiritual progress, rather than treating astrology as a binding forecast.
