Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
द्विघ्नं जीवाथ जीवार्द्धवर्गे शरहृते युते । व्यासोष्टतेभवेदेवं प्रोक्तं गणितकोविदैः ॥ ४८ ॥
dvighnaṃ jīvātha jīvārddhavarge śarahṛte yute | vyāsoṣṭatebhavedevaṃ proktaṃ gaṇitakovidaiḥ || 48 ||
« D’abord, double la quantité appelée jīva; puis ajoute-la au carré de la moitié de jīva, et ajoute encore la valeur obtenue après avoir retranché cinq. Ainsi le résultat devient “vingt-huit” », telle est l’énonciation des connaisseurs en mathématiques.
Sanatkumara (teaching Narada in a technical/vedāṅga-style exposition)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It shows that Moksha-Dharma teaching in the Narada Purana also preserves śāstric disciplines like gaṇita—training the mind in precision, pramāṇa (valid measurement), and disciplined reasoning that supports higher inquiry.
This specific verse is not a bhakti instruction; it is a technical gaṇita rule. In the wider Narada–Sanatkumara dialogue, such disciplines function as supportive knowledge, while devotion to Vishnu remains the primary liberating path.
Gaṇita-style computation using symbolic numerals (e.g., śara = 5) and algebraic operations (doubling, squaring, adding/subtracting) is highlighted—useful for calendrics, astronomy (jyotiṣa), and ritual measurements.
