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 ||
Karena guṇa-guṇanya mengalami susut dan luluh, Prakṛti dipandang dapat binasa; tetapi karena Puruṣa adalah penggerak dan pelaku batin, orang bijak menyatakannya tak binasa. Wahai raja para Gandharva, inilah ajaran keempat tentang penyelidikan (ānvīkṣikī) yang telah kuajarkan kepadamu—pengetahuan yang menuntun pada tujuan tertinggi dan menyokong pembebasan.
याज़्ञवल्क्य उवाच
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.
