Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
युग्मवृत्तेधनर्णश्यादोजादूनेऽधिके स्फुटम् । तद्गुणे भुजकोटिज्येभगणांशविभाजिते ॥ १०६ ॥
yugmavṛttedhanarṇaśyādojādūne'dhike sphuṭam | tadguṇe bhujakoṭijyebhagaṇāṃśavibhājite || 106 ||
یُگم دائرے میں مثبت و منفی کا لحاظ رکھا جائے؛ ‘اوج’ حصہ کم ہو تو بڑھایا جائے اور زیادہ ہو تو گھٹایا جائے—یوں صاف (درست) قدر حاصل ہوتی ہے۔ پھر اسی سے ضرب دے کر اور بھگن-اَمش کے مناسب حصے سے تقسیم کرنے پر بھُج-جیا اور کوٹی-جیا حاصل ہوتی ہیں۔

It frames precise calculation (sphuṭa—true value) as part of dharmic knowledge: correct measures and truthful computation support right ritual timing and disciplined practice, which in turn aids the pursuit of mokṣa.
Indirectly: by emphasizing accurate determination of values used in calendrical/astronomical contexts, it supports proper observance of vows and sacred timings (which are often dedicated to Viṣṇu-bhakti), ensuring devotion is practiced with correctness and steadiness.
Vedāṅga Jyotiṣa/Gaṇita: handling positive/negative results (dhana/ṛṇa), applying correction to obtain sphuṭa values, and computing bhujajyā and koṭijyā (sine components) via division by a bhagaṇa-aṃśa factor.
