Impermanence, Svabhāva, and Śuka’s Resolve for Yoga
पज्चविंशतिमं प्रश्न॑ पप्रच्छान्वीक्षिकी तदा । विश्वाविश्वं तथाश्चाश्वृं मित्र वरुणमेव च
pañcaviṁśatitamaṁ praśnaṁ papracchānvīkṣikī tadā | viśvāviśvaṁ tathā cāśvaṁ mitra varuṇam eva ca pṛthvīnātha |
Yājñavalkya said: “Then he posed the twenty-fifth question, concerning the discipline of rational inquiry (Ānvīkṣikī). O lord of the earth, after asking twenty-four questions about the Veda, he next asked: ‘What is the all (viśvā)? What is the not-all (aviśva)? What is the horse (aśva)? What is the non-horse (an-aśva)? What is Mitra? What is Varuṇa?’”

The verse frames a shift from purely Vedic questioning to Ānvīkṣikī—disciplined rational inquiry—by posing paired contrast-questions (all/not-all, horse/non-horse) and invoking Vedic deities (Mitra, Varuṇa). It highlights that understanding dharma and reality involves both scriptural tradition and careful conceptual analysis.
Yājñavalkya reports that, after a set of twenty-four questions about the Veda, the interlocutor raises the twenty-fifth question concerning Ānvīkṣikī and lists specific items to be defined or understood: viśvā, aviśva, aśva, non-aśva, and the deities Mitra and Varuṇa.
