Shloka 19
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:
tadā tam anupaśyet yasmin dṛṣṭe na kathyate | hṛdayastho 'ntarātmeti jñeyo jñastāta madvidhaiḥ ||
于是应当观见“彼”—一旦得见，言语便归于寂然。那住于心中的内在自我，应知为内我（Antarātman），为一切知者。孩子啊，对于像我这样的人，理当寻求并获得对那内在见证者的认识：祂知一切，住在每个人的心中——尤其在瑜伽之时，瑜伽行者于内直接证见至上者。

Educational Q&A
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.
