Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
स्वाक्षार्कनतभागानां दिक्साम्येऽतरमन्यथा । दिग्भेदोपक्रमः शेषस्तस्य ज्या त्रिज्यया हता ॥ १४१ ॥
svākṣārkanatabhāgānāṃ diksāmye'taramanyathā | digbhedopakramaḥ śeṣastasya jyā trijyayā hatā || 141 ||
স্বাক্ষ আৰু সূৰ্য-নতি অংশসমূহত দিক্সাম্য থাকিলে বিকল্প পদ্ধতি গ্ৰহণ কৰিব লাগে; নহ’লে দিগ্ভেদৰ পৰা উপক্রম কৰি অৱশিষ্ট অংশ সামৰিব লাগে। সেই শেষৰ জ্যা ত্ৰিজ্যা দ্বাৰা গুণিলে প্ৰয়োজনীয় মান পোৱা যায়।

It highlights that dharma and ritual timing rely on precise knowledge (Jyotiṣa/Vedāṅga); disciplined calculation is presented as a supportive limb for right practice and clarity of conduct.
Indirectly: it supports Bhakti-driven worship by ensuring correct astronomical determinations (directions, residual arcs, sine-based results) used for proper observances, aligning devotion with accurate sacred timing.
Jyotiṣa/Gaṇita: handling directional symmetry vs. asymmetry, using the remainder (śeṣa) and computing a result via jyā (sine) multiplied by trijyā (radius).
