Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
साक्षार्कापक्रमयुतिर्द्दिक्साम्येंतरमन्यथा । शेषह्यानांशाः सूर्यस्य तद्वाहुज्याथ कोटिजाः ॥ १३९ ॥
sākṣārkāpakramayutirddiksāmyeṃtaramanyathā | śeṣahyānāṃśāḥ sūryasya tadvāhujyātha koṭijāḥ || 139 ||
جب سورج کا اَپَکرم دِکْسامْیَ (اعتدالی سمت) کے ساتھ براہِ راست مل جائے تو نتیجہ حاصل ہوتا ہے؛ ورنہ دوسری طرح حساب کیا جاتا ہے۔ باقی حصے سورج کے لطیف اَناںش ہیں؛ انہی سے بہوجیا اور کوٹی جیا کے پیمانے نکالے جاتے ہیں۔
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.
