Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
साक्षार्कापक्रमयुतिर्द्दिक्साम्येंतरमन्यथा । शेषह्यानांशाः सूर्यस्य तद्वाहुज्याथ कोटिजाः ॥ १३९ ॥
sākṣārkāpakramayutirddiksāmyeṃtaramanyathā | śeṣahyānāṃśāḥ sūryasya tadvāhujyātha koṭijāḥ || 139 ||
যেতিয়া সূৰ্যৰ অপক্রম দিক্সাম্য (বিষুৱ-দিশ)ৰ সৈতে সোজাকৈ যুক্ত হয়, তেতিয়া ফল পোৱা যায়; নহ’লে অন্য ধৰণে গণনা কৰিব লাগে। অৱশিষ্ট অংশসমূহ সূৰ্যৰ সূক্ষ্ম অণাংশ; তাৰ পৰা বহুজ্যা আৰু কোটিজ্যা নিৰ্ণীত হয়।
Sanatkumara (in dialogue with Narada, within the Moksha Dharma discourse that includes technical cosmology/astronomy)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It shows that dharma and higher aims (including moksha-oriented discipline) are supported by precise knowledge of time and cosmos; correct understanding of the Sun’s motion underpins sacred calendrical order.
Indirectly: by emphasizing accurate time-reckoning for vrata, pūjā, and sacred observances, it supports disciplined devotional practice even though the verse itself is technical (Jyotiṣa) rather than devotional poetry.
Vedāṅga Jyotiṣa: computation of solar declination (apakrama) and related trigonometric measures—jyā (sine/cord) and koṭi-jyā (cosine)—used in traditional astronomical calculation.
