Impermanence, Svabhāva, and Śuka’s Resolve for Yoga
चतुर्थी राजशार्दूल विद्यैषा साम्परायिकी । उदीरिता मया तुभ्यं पजचविंशादधिषछिता
caturthī rājaśārdūla vidyaiṣā sāmparāyikī | udīritā mayā tubhyaṃ pañcaviṃśād adhiṣṭhitā ||
「王たちの中の虎よ、これが第四の教えである—来世と霊我の究竟の行路に関わるものだ。真の分別を支える二十五の原理(タットヴァ)に拠って、私はそれを汝に宣示した。」
याज़्ञवल्क्य उवाच
Yājñavalkya identifies this as the ‘fourth’ doctrine aimed at the highest welfare beyond death, grounding it in the framework of the twenty-five tattvas—an analytical, Sāṃkhya-like account meant to cultivate discrimination and liberation-oriented understanding.
In a didactic exchange within Śānti Parva, Yājñavalkya addresses a king respectfully and concludes or marks a section of instruction, stating that he has taught a doctrine concerning the hereafter, structured upon the twenty-five principles.
