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 ||
“Primero duplica la cantidad llamada jīva; luego súmala al cuadrado de la mitad de jīva, y añade también la cantidad obtenida tras restar cinco. De este modo el resultado llega a ‘veintiocho’”, así lo han declarado los versados en matemática.
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.
