Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning

Devanagari script

युग्मवृत्तेधनर्णश्यादोजादूनेऽधिके स्फुटम् । तद्गुणे भुजकोटिज्येभगणांशविभाजिते ॥ १०६ ॥

Transliteration

yugmavṛttedhanarṇaśyādojādūne'dhike sphuṭam | tadguṇe bhujakoṭijyebhagaṇāṃśavibhājite || 106 ||

Translation

Trong vòng tròn chẵn (yugma), kết quả phải được xét theo dấu dương hay âm: khi phần lẻ bị thiếu thì tăng lên, khi quá thừa thì giảm xuống, để được giá trị rõ ràng (đã hiệu chỉnh). Nhân theo giá trị ấy, rồi chia theo phần thích hợp của các độ quay hoàng đạo (bhagaṇa-aṃśa), sẽ thu được bhuja-jyā (sin của đáy) và koṭi-jyā (sin của đường vuông góc).

FAQs

What is the spiritual significance of this verse in Narada Purana?

It frames precise calculation (sphuṭa—true value) as part of dharmic knowledge: correct measures and truthful computation support right ritual timing and disciplined practice, which in turn aids the pursuit of mokṣa.

How does this verse explain the path of devotion (Bhakti)?

Indirectly: by emphasizing accurate determination of values used in calendrical/astronomical contexts, it supports proper observance of vows and sacred timings (which are often dedicated to Viṣṇu-bhakti), ensuring devotion is practiced with correctness and steadiness.

What practical Vedic knowledge (Vedanga) is highlighted here?

Vedāṅga Jyotiṣa/Gaṇita: handling positive/negative results (dhana/ṛṇa), applying correction to obtain sphuṭa values, and computing bhujajyā and koṭijyā (sine components) via division by a bhagaṇa-aṃśa factor.
