Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
पृथक् तत्क्रांत्यक्षभागसंस्कृतौ स्युर्नतांशकाः । तद्दिघ्नांशकृतिद्व्यूनार्द्धार्कयुता हरिः ॥ १५९ ॥
pṛthak tatkrāṃtyakṣabhāgasaṃskṛtau syurnatāṃśakāḥ | taddighnāṃśakṛtidvyūnārddhārkayutā hariḥ || 159 ||
کرانتی-اَمش اور اَکش-بھاغ کو جدا جدا سنسکار کرنے سے جو مقداریں حاصل ہوں، وہ ‘نَتَامشَک’ کہلاتی ہیں۔ اسی بنیاد پر دوگنا مربع وغیرہ کر کے، دو کم کر کے اور نصف-آرک شامل کر کے ‘ہری’ (مقسوم علیہ) متعین ہوتا ہے۔
Sanatkumara (teaching technical computation to Narada in the Moksha Dharma section, with Vedanga-style astronomical rules)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It shows that Moksha-oriented life in the Purana also relies on precise Vedanga knowledge—especially Jyotisha—for correct timing of dharma, vrata, and sacred observances, supporting disciplined practice.
Indirectly: accurate astronomical computation supports proper observance of devotional vows and holy days; correct timing strengthens niyama (religious discipline) that sustains Vishnu-bhakti in practice.
Jyotisha Vedanga—procedural calculation involving krānti (declination), akṣa (latitude), natāṃśa components, and a defined divisor (harī) used in computational steps.
