FAQs
It shows that Moksha-Dharma teaching in the Narada Purana also preserves Vedāṅga knowledge—disciplined time-reckoning and precise calculation—supporting correct timing for dharmic practice and study.
Indirectly: accurate Jyotiṣa calculation is presented as a supporting limb for dharma (right timing and order), which helps a devotee maintain steady sādhana; the verse itself is primarily technical rather than devotional.
Vedāṅga Jyotiṣa/astronomical computation: use of nata-nāḍī (gnomon/shadow-based measures), reference rising-time units (Laṅkā-udaya asu), and adjustment by fractional increase/decrease for determining a derived quantity (vyaya-aṃśa) when Mars is in the ascendant.
