Impermanence, Svabhāva, and Śuka’s Resolve for Yoga
गुणक्षयत्वात् प्रकृति: कर्तृत्वादक्षयं बुधा: । एषा ते<<न्वीक्षिकी विद्या चतुर्थी साम्परायिकी
guṇakṣayatvāt prakṛtiḥ kartṛtvād akṣayaṃ budhāḥ | eṣā te ’nvīkṣikī vidyā caturthī sāmparāyikī ||
ਗੁਣਾਂ ਦੇ ਖ਼ਤਮ ਹੋਣ ਕਰਕੇ ਪ੍ਰਕ੍ਰਿਤੀ ਨੂੰ ਨਾਸਵੰਤ ਮੰਨਿਆ ਜਾਂਦਾ ਹੈ; ਪਰ ਕਰਤ੍ਰਿਤ੍ਵ—ਅੰਦਰੂਨੀ ਪ੍ਰੇਰਕ ਹੋਣ ਕਰਕੇ—ਬੁੱਧਿਮਾਨ ਪੁਰੁਸ਼ ਨੂੰ ਅਕ੍ਸ਼ਯ ਕਹਿੰਦੇ ਹਨ। ਹੇ ਗੰਧਰਵ-ਰਾਜ! ਇਹ ਚੌਥੀ ਆਨ੍ਵੀਕ੍ਸ਼ਿਕੀ ਵਿਦਿਆ, ਜੋ ਪਰਮਾਰਥ (ਮੋਖ਼ਸ਼) ਵਿੱਚ ਸਹਾਇਕ ਹੈ, ਮੈਂ ਤੈਨੂੰ ਦੱਸੀ।

The verse distinguishes prakṛti and puruṣa: prakṛti is perishable because it is constituted by guṇas that undergo change and dissolution, while puruṣa is imperishable as the inner principle associated with agency/instigation. This discrimination is presented as ānvīkṣikī—philosophical inquiry—aimed at the highest good (mokṣa).
Yājñavalkya addresses the Gandharva king and concludes a segment of instruction by presenting a doctrinal summary: he has taught a ‘fourth’ ānvīkṣikī vidyā, characterized as sāmparāyikī—knowledge oriented toward the ultimate end and liberation.
