Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
शनिपातस्य भगणाः कल्पे यमरसर्तवः । वर्तमानयुगे पानावत्सराभगणाभिधाः ॥ ७६ ॥
śanipātasya bhagaṇāḥ kalpe yamarasartavaḥ | vartamānayuge pānāvatsarābhagaṇābhidhāḥ || 76 ||
Dans un Kalpa, les cycles (bhagaṇa) liés aux conjonctions de Saturne portent le nom « Yama–Rasa–Ṛtavaḥ » ; et dans le Yuga actuel, ils sont connus sous l’appellation « Pānāvat-sarā-bhagaṇa ».
Sanatkumara (teaching Narada in a technical enumeration of time/astronomical reckoning)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It frames cosmic time (Kalpa/Yuga) as a measurable, ordered structure; such time-reckoning supports dharma by correctly situating rites, vows, and observances within the sacred calendar.
Indirectly: by emphasizing accurate calendrical knowledge, it safeguards proper timing of devotional observances (vratas, fasts, and worship), which are core supports for steady Vishnu-bhakti in Purāṇic practice.
