Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
क्रांत्योर्जेत्रिज्ययाभिस्ते परमायक्रमोद्धते । तच्चापांतर्मर्द्धवायोर्ज्यभाविनशीतगौ ॥ १७९ ॥
krāṃtyorjetrijyayābhiste paramāyakramoddhate | taccāpāṃtarmarddhavāyorjyabhāvinaśītagau || 179 ||
Durch Maße, die aus Sehne und Sinus der solstitialen Deklinationen gewonnen werden, erlangt man das höchste, erhabene Verfahren der Berechnung. Daraus ergibt sich, indem man innerhalb des Bogens wirkt—durch die Kraft des „inneren Windes“ (die operative Rechenkraft)—dass die entstehenden Sinus Kälte und Hitze, also die Wirkungen der Jahreszeiten, anzeigen.
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.
