Indirectly: by teaching reliable astronomical computation, it supports proper observance of vows and festivals (vrata, parva) that structure devotional practice toward Vishnu and other deities.
Jyotiṣa-vedāṅga: mathematical methods for mean/true planetary positions, applied problem-solving (anuyoga), and calculation of lunar and solar eclipses (grahaṇa).
