Shloka 21
Adhyātma–Adhibhūta–Adhidaivata Correspondences and the Triguṇa Lakṣaṇas (Śānti-parva 301)
तेजो वायौ तु संसक्त वायुं नभसि चाश्रितम् | नभो महति संयुक्त महद् बुद्धौ च संश्रितम्
tejo vāyau tu saṁsaktaṁ vāyuṁ nabhasi cāśritam | nabho mahati saṁyuktaṁ mahad buddhau ca saṁśritam ||
毗湿摩说道：“光辉（tejas，火）与风相系；风依止于虚空。虚空与大原理（mahat）相合，而大原理又以宇宙之智（buddhi）为所依。”在此教诲中，毗湿摩追溯微细元素与内在原理之间的依持之链，劝人以观照之心明白：显现之世如何依赖更微细的因与其统摄。

Educational Q&A
That the manifest elements and forces are mutually dependent and ultimately grounded in subtler principles (space, mahat, buddhi). The verse encourages seeing causality and support-relationships behind appearances, a step toward discernment (viveka) and dharmic clarity.
In Shanti Parva, Bhishma instructs Yudhishthira on higher knowledge and right understanding. Here he presents a Sāṅkhya-like sequence linking the elements (fire, wind, space) to cosmic principles (mahat, buddhi) to explain how the world is structured and sustained.
