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 ||
ఉత్క్రమంగా (విపరీత క్రమంలో) ఈ ఆరుగూ ఇష్టమైనవిగా భావించబడతాయి—తులా మొదలుకొని. గత-భోగ్య (ఇప్పటికే గడిచిన/అనుభవించిన) భాగపు ప్రమాణాలను గణించాలి; అలాగే తన ఇష్ట భాస్కరుని సాయన (అయన/వంగింపు)ను నిర్ణయించాలి.
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.
