अव्यक्त–पुरुष–विवेकः (Discrimination of Avyakta/Prakṛti and Puruṣa) — Yājñavalkya’s Anvīkṣikī to Viśvāvasu
तदा तमनुपश्येत यस्मिन् दृष्टे न कथ्यते । हृदयस्थो<न्तरात्मेति ज्ञेयो ज्ञस्तात मद्धिधै:,जिनका साक्षात्कार कर लेनेपर मनुष्य कुछ बोल नहीं पाता, योगकालमें योगी उसी परमात्माको देखे। वत्स! मुझ-जैसे लोगोंको अपने-अपने हृदयमें स्थित सबके ज्ञाता अन्तरात्माका ही ज्ञान प्राप्त करना उचित है
tadā tam anupaśyet yasmin dṛṣṭe na kathyate | hṛdayastho 'ntarātmeti jñeyo jñastāta madvidhaiḥ ||
Then one should behold That—upon seeing which speech falls silent. That Inner Self, abiding in the heart, is to be known as the indwelling Ātman, the all-knower. Dear child, for people like me it is fitting to seek and attain the knowledge of that inner witness who knows all and resides in each one’s heart—especially in the time of yoga, when the yogin directly perceives the Supreme within.
वसिष्ठ उवाच
The verse teaches that the highest reality—the Inner Self dwelling in the heart—is directly knowable in yogic realization, yet it transcends verbal description. True knowledge culminates in inward vision of the all-knowing witness (antarātmā), where speech and conceptualization fall silent.
Vasiṣṭha addresses a disciple affectionately (“tāta”) and instructs him on contemplative practice: in the proper yogic time/state, one should behold the indwelling Self. The emphasis is on interior realization rather than external debate—pointing to the heart as the locus of the supreme, all-knowing presence.
