Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
क्रांत्योर्जेत्रिज्ययाभिस्ते परमायक्रमोद्धते । तच्चापांतर्मर्द्धवायोर्ज्यभाविनशीतगौ ॥ १७९ ॥
krāṃtyorjetrijyayābhiste paramāyakramoddhate | taccāpāṃtarmarddhavāyorjyabhāvinaśītagau || 179 ||
وبالمقادير المستخرجة من الوتر وجيب ميول الانقلابين، يُنال أسمى منهجٍ رفيعٍ في الحساب. ومن ذلك، بالعمل داخل القوس—بفعل «الريح الباطنة» (أي القوة المُشغِّلة في الحساب)—تُظهر الجيوب الناتجة البردَ والحرَّ، أي آثار الفصول.
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.
