Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
त्रिंशत्कृत्योयुगे भानां चक्रं प्राक्परिलंबते । तद्गुणाद्भदिनैर्भक्त्या द्युगणाद्यदवाप्यते ॥ १३६ ॥
triṃśatkṛtyoyuge bhānāṃ cakraṃ prākparilaṃbate | tadguṇādbhadinairbhaktyā dyugaṇādyadavāpyate || 136 ||
في يوجا واحدة تُتمّ دورة الشمس—عجلة الأنوار—دورانها بعد ثلاثين تكرارًا؛ وبخاصّتها تُستخرج حصيلة الأيام بحساب مجموعات الأيام، بمواظبةٍ كأنها انتباهٌ تعبّديّ (بهاكتي).
Sanatkumara (in dialogue instruction to Narada on dharma/knowledge; technical reckoning framed as disciplined practice)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It frames precise time-reckoning (kāla-gaṇanā) as a disciplined, reverent practice—showing that knowledge, order, and careful attention can support dharma and spiritual life.
The word “bhaktyā” indicates doing even technical reckoning with devoted diligence—turning study and calculation into a form of sincere, attentive service rather than mere dry scholarship.
Vedāṅga Jyotiṣa (astronomical/astrological timekeeping): it points to computing cycles and deriving day-counts via grouped day-reckoning (dyu-gaṇa) within a yuga framework.
