Jyotiṣa-saṅgraha: Varga-vibhāga, Bala-nirṇaya, Garbha-phala, Āyuḥ-gaṇanā
एतद्योगजमायुः स्यादथ स्पष्टमुदीयते । सूर्याधिक बले पैंडं निसर्गाञ्च विधोर्बले ॥ ११९ ॥
etadyogajamāyuḥ syādatha spaṣṭamudīyate | sūryādhika bale paiṃḍaṃ nisargāñca vidhorbale || 119 ||
یہی عمرِ یوگج کہی گئی ہے؛ اب بات صاف بیان ہوتی ہے۔ جب سورج کی قوت غالب ہو تو پَیṇḍ (حسابی) عمر لی جائے، اور جب چاند کی قوت غالب ہو تو نِسَرگ (طبعی) حصہ اختیار کیا جائے۔

It frames longevity as governed by cosmic order (graha-bala) and disciplined knowledge (śāstra), encouraging a dharmic life aligned with time (kāla) rather than fatalism.
Indirectly: by showing that life-span is variable and time-bound, it supports the Purāṇic emphasis on using one’s allotted time for sādhana—especially remembrance and devotion—rather than mere calculation.
Vedāṅga Jyotiṣa: assessing āyuḥ (longevity) through comparative strength (bala) of the Sun and Moon, and applying different lifespan measures (paiṇḍa vs. nisarga) accordingly.
