Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
रवींद्वोर्मानयोगार्द्धं षष्ट्या संगुण्य भाजयेत् । तयोर्भुक्तयंतरेणाप्तं स्थित्यमर्द्धां नाडिकादिवत् ॥ १८४ ॥
ravīṃdvormānayogārddhaṃ ṣaṣṭyā saṃguṇya bhājayet | tayorbhuktayaṃtareṇāptaṃ sthityamarddhāṃ nāḍikādivat || 184 ||
সূৰ্য আৰু চন্দ্ৰৰ সংযুক্ত মানৰ অর্ধাংশ লৈ তাক ষাঠি গুণ কৰি ভাগ কৰিব লাগে। তাৰ পিছত তেওঁলোকৰ দৈনিক গতি-ভেদে ভাগ কৰিলে যি ফল পোৱা যায়, সেয়াই নাড়িকা আদি এককত প্ৰকাশিত তেওঁলোকৰ ‘স্থিতি’ (সংযোগ/বিয়োগ) ৰ অর্ধকাল।
Narada (teaching a technical rule within the Moksha-Dharma section, drawing on Vedanga-style computation)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It shows that Dharma and Moksha-oriented life in the Narada Purana is supported by precise kāla-nirṇaya (time-determination), because correct timing underlies vrata, japa, and other sacred observances.
Bhakti practices often depend on proper tithi and lunar-solar calculations; this verse provides a computational tool so devotional rites can be performed at the intended sacred time without error.
Vedāṅga Jyotiṣa: using the Sun–Moon measures, their bhukti (daily motion), and nāḍikā-based time units to compute the duration of a celestial condition (their ‘stay’).
