Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
कालांशास्तैरूनयुक्ते रवौ ह्यस्तोदयौ विधोः । दृष्ट्वा ह्यादौ खेटबिंबं दृगौञ्च्ये लंबमीक्ष्य च ॥ १६६ ॥
kālāṃśāstairūnayukte ravau hyastodayau vidhoḥ | dṛṣṭvā hyādau kheṭabiṃbaṃ dṛgauñcye laṃbamīkṣya ca || 166 ||
સૂર્યના કાલાંશને તે રીતે હીન‑યુત કરીને યોગ્ય કર્યા પછી ચંદ્રના અસ્ત‑ઉદય નક્કી કરો. પ્રથમ ખગોળીય બિંબ જોઈ, દૃષ્ટિ ગોઠવી લંબ રેખા પણ નિહાળો।

It treats disciplined observation and correct time‑reckoning (kāla-gananā) as part of dharmic order, showing that accurate knowledge of time supports right ritual timing and a life aligned with cosmic law.
Indirectly: by emphasizing correct determination of lunar timings, it supports proper observance of vows and worship schedules (often lunar-based), which strengthens steady devotional practice.
Vedāṅga Jyotiṣa—using kālāṃśa corrections and direct sighting of the luminary’s disc, along with vertical (laṃba) alignment, to determine the Moon’s rising and setting.
