In Jain intellectual history, astronomy (often treated under jyotiṣa, gaṇitāṅga, and cosmological sections of canonical texts) is not a separate natural science in the modern sense but an integrated discipline combining cosmology, time‑cycles, spatial structure, and karmic ontology.

It functions as the axia… at the center. Celestial bodies such as the sun (sūrya) and moon (candra) are described as luminous entities carried by divine attendants, with their motions explained through karmic and cosmic mechanisms rather than gravitational physics.

These cycles influence the conditions of life, longevity, and moral capacity. Astronomical phenomena—eclipses, planetary movements, and stellar configurations—are interpreted through karmic causality and the actions of celestial beings, not through physical laws.
