Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
क्रांत्योर्जेत्रिज्ययाभिस्ते परमायक्रमोद्धते । तच्चापांतर्मर्द्धवायोर्ज्यभाविनशीतगौ ॥ १७९ ॥
krāṃtyorjetrijyayābhiste paramāyakramoddhate | taccāpāṃtarmarddhavāyorjyabhāvinaśītagau || 179 ||
अयन-क्रांतींच्या ज्या व त्रिज्यांपासून तो परम, उन्नत गणनाक्रम सिद्ध होतो. मग चापाच्या अंतरी ‘अंतर्वायू’च्या क्रियेमुळे उत्पन्न झालेल्या ज्या शीत व उष्ण—ऋतुफळ—दाखवितात.
Narada (in dialogue context with Sanatkumara tradition; technical exposition within Moksha Dharma section)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It links precise knowledge of time and cosmic order (kāla and graha-gati) with dharma-oriented living, implying that disciplined understanding of the cosmos supports right conduct and steadiness on the moksha path.
Indirectly: by emphasizing accurate reckoning of seasonal/time cycles, it supports proper observance of vrata, worship timings, and sacred days—practices that structure and deepen Vishnu-bhakti even when the verse itself is technical.
Vedāṅga Jyotiṣa (astronomy/astrology) and computational practice (gaṇita): using krānti (declination), cāpa (arc), and jyā (sine/chord relations) to infer seasonal cold/heat and refine calendrical calculations.
