Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
उत्क्रमेण षडेवैते भवंतीष्टास्तुलादयः । गतभोग्यासवः कार्याः सायनास्स्वेष्टभास्कराः ॥ १४८ ॥
utkrameṇa ṣaḍevaite bhavaṃtīṣṭāstulādayaḥ | gatabhogyāsavaḥ kāryāḥ sāyanāssveṣṭabhāskarāḥ || 148 ||
ഉത്ക്രമത്തിൽ (വിപരീതക്രമത്തിൽ) ഈ ആറും ഇഷ്ടം—തുല മുതൽ ആരംഭിച്ച്. ഗത-ഭോഗ്യ (ഇതിനകം അനുഭവിച്ച) ഭാഗത്തിന്റെ അളവുകൾ കണക്കാക്കണം; കൂടാതെ സ്വന്തം ഇഷ്ട-ഭാസ്കരന്റെ സായന (അയനം/ചായവ്)യും നിർണ്ണയിക്കണം.
Sanatkumara (teaching Narada in a technical/Vedanga-style passage)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It shows that even within Moksha-oriented teaching, the Purana preserves disciplined Vedanga (Jyotiṣa) method—urging orderly calculation (sequence, elapsed span, solar reference) so that dharmic decisions are made with clarity and correctness.
Indirectly: it frames technical knowledge as supportive to dharma-based living, which in the Narada tradition becomes a stable foundation for Vishnu-bhakti—right timing and right understanding reduce confusion and strengthen steady devotional practice.
Jyotiṣa (Vedic astronomy/astrology): using an ordered set of zodiacal signs (starting from Tulā), calculating elapsed/enjoyed life-period indicators, and applying the sāyana (ayana/declination) solar reference for accurate computation.
