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 ||
گُṇوں کے زوال کے سبب پرکرتی کو فانی مانا گیا ہے؛ اور کرتृत्व—یعنی باطنی محرّک و عامل—ہونے کے سبب داناؤں نے پُرُش کو اَکشَی کہا ہے۔ اے گندھرو ں کے راجا! یہ چوتھی آنوِیکشِکی وِدیا، جو پرمارْتھ (موکش) میں مددگار ہے، میں نے تجھے بتائی۔

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.
