Nārada’s Darśana of Viśvarūpa Nārāyaṇa and the Caturmūrti Doctrine (नारदस्य नारायणदर्शनं चतुर्मूर्तिविचारश्च)
तम: परिगतं वेश्म यथा दीपेन दृश्यते । तथा बुद्धिप्रदीपेन शक््य आत्मा निरीक्षितुम्
tamaḥ parigataṁ veśma yathā dīpena dṛśyate | tathā buddhi-pradīpena śakya ātmā nirīkṣitum ||
ジャナカは教える。闇に覆われた家が灯火によって見えるように、無明の闇に隠された真我もまた、清められた बुद्धि（知性）の灯によって直に見極められる。

Educational Q&A
The Self is not grasped by external means; it is revealed when ignorance (tamas) is dispelled by the illuminating power of purified intellect (buddhi) functioning as a lamp—i.e., discriminative knowledge leading to direct insight.
King Janaka is speaking in a didactic context within Śānti Parva, using a simple analogy (lamp and dark house) to explain how inner illumination through buddhi enables realization of the Ātman obscured by ignorance.
