पिंडे निसर्गे रवोच्चे नो ग्रहः षट्भाल्पको यदा । चक्रशुद्धस्तदा ग्राह्येस्यांशा आयुषिसंमताः ॥ १२२ ॥
piṃḍe nisarge ravocce no grahaḥ ṣaṭbhālpako yadā | cakraśuddhastadā grāhyesyāṃśā āyuṣisaṃmatāḥ || 122 ||
出生時の身体配置(piṇḍa)において、太陽が高揚位におらず、いずれの惑星も六バ―ガ(bhāga)だけ弱まっていないなら、その星位図は「浄化された」と見なされる。採るべき度分(aṁśa)は、寿命判定に公認されたものとする。

It frames Jyotiṣa as a disciplined, rule-based Vedāṅga: only when the chart is ‘śuddha’ (free from specified weaknesses) should one rely on its aṁśas for conclusions like longevity—encouraging careful, ethical discernment rather than superstition.
Indirectly: by emphasizing correct assessment of worldly conditions (like āyus), it supports a dharmic life where one uses knowledge responsibly and turns the mind toward higher aims (mokṣa), for which bhakti is a central means in the Narada Purana.
Vedāṅga Jyotiṣa—evaluating planetary strength/weakness and using aṁśa (degree/divisional) measures to judge whether a horoscope is fit for reliable āyus (longevity) computation.
