Adhyātma–Adhibhūta–Adhidaivata Correspondences and the Triguṇa Lakṣaṇas (Śānti-parva 301)
द्विगुणं च रजो ज्ञात्वा सत्त्वमेकगुणं पुन: । मार्ग विज्ञाय तत्त्वेन प्रलये प्रेक्षणे तथा
dviguṇaṁ ca rajo jñātvā sattvam ekaguṇaṁ punaḥ | mārgaṁ vijñāya tattvena pralaye prekṣaṇe tathā ||
毗湿摩说：既已了知“罗阇斯”(rajas)具二重相，而“萨埵”(sattva)在其本性上复为一味；又如实辨明正道，并洞察劫坏之理（pralaya）与内观之修（观照省察），则能连同其过患而裁量诸根境界，并以正智趋向解脱。

Educational Q&A
The verse emphasizes discriminative knowledge of the guṇas—especially the structure of rajas and sattva—and insists that liberation-oriented practice depends on grasping the true path along with the principles of dissolution (pralaya) and contemplative inner examination (prekṣaṇa).
In Śānti Parva, Bhishma continues his post-war instruction to Yudhishthira, shifting from external duties to inner disciplines: analysis of nature (guṇas), correct discernment of the path, and contemplative insight that supports renunciation and liberation.
