Narada Purana — Purva Bhaga, Shloka 110

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

Devanagari script

तद्बाहुफलवर्गैक्यान्मूलं कर्णश्चलाभिधः । त्रिज्याभघ्यस्तं भुजफलं पलकर्णविभाजितम् ॥ ११० ॥

Transliteration

tadbāhuphalavargaikyānmūlaṃ karṇaścalābhidhaḥ | trijyābhaghyastaṃ bhujaphalaṃ palakarṇavibhājitam || 110 ||

Translation

La raíz cuadrada de la suma de los cuadrados de esos dos resultados laterales se llama karṇa (hipotenusa), también denominada calā. El resultado lateral deseado (bhujaphala) se obtiene multiplicándolo por la trijyā (radio) y dividiéndolo luego por la hipotenusa (aquí llamada pala-karṇa).

Word by Word

• तत्-बाहु-फल-वर्ग-ऐक्यात्: from the sum/unity of the square of that sine-value
• तत्-बाहु-फल-वर्ग-ऐक्यात्: अपादान (Source/Ablative/अपादान)
• Type: Noun
• Root: तत् (सर्वनाम-प्रातिपदिक) + बाहु (प्रातिपदिक) + फल (प्रातिपदिक) + वर्ग (प्रातिपदिक) + ऐक्य (प्रातिपदिक)
• Form: नपुंसकलिङ्ग, पञ्चमी एकवचन; समासः (बहुपद-तत्पुरुष): ‘तत् बाहुफलस्य वर्गस्य ऐक्यात्’ = from the unity/sum of the square of that sine-value; अपादानार्थे (ablative)

• मूलम्: the square root
• मूलम्: कर्म (Object/कर्म)
• Type: Noun
• Root: मूल (प्रातिपदिक)
• Form: नपुंसकलिङ्ग, प्रथमा/द्वितीया एकवचन

• कर्णः: the hypotenuse (karṇa)
• कर्णः: कर्ता (Subject/कर्ता)

• Type: Adjective
• Root: त्रिज्या (प्रातिपदिक) + अभ (प्रातिपदिक/उपसर्गवत्) + घ्यस्त (कृदन्त; √घस्/√हन्? पाठभेद; here intended ‘अभ्यस्त’ = multiplied)
• Form: नपुंसकलिङ्ग, प्रथमा/द्वितीया एकवचन; पाठभेदः ‘अभघ्यस्त’ सम्भवतः ‘अभ्यस्त’; अर्थतः ‘त्रिज्यया अभ्यस्तम्’ = multiplied by radius; विशेषणम्

• भुज-फलम्: sine value
• भुज-फलम्: कर्म (Object/कर्म)
• Type: Noun
• Root: भुज (प्रातिपदिक) + फल (प्रातिपदिक)

FAQs

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

It shows that Moksha Dharma is supported by disciplined śāstric knowledge—precise calculation and right understanding (pramāṇa) are treated as aids to clarity, which ultimately supports dharma and inner steadiness.

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

Indirectly: by valuing exact śāstra-based methods used in dharma (such as timing and measurement), it supports orderly practice; such orderliness becomes a practical support for steady Vishnu-bhakti rather than replacing devotion itself.

What practical Vedic knowledge (Vedanga) is highlighted here?

Vedāṅga Jyotiṣa/gaṇita-style computation: a rule akin to the Pythagorean relation for determining the karṇa (hypotenuse) and deriving a side value via multiplication by trijyā (radius) and division by the computed karṇa.
