Shloka 10
नागैः सह ब्राह्मणस्य अतिथिधर्म-व्रतसंवादः | The Brahmin’s Vow and the Nāgas’ Hospitality Appeal
तस्माच्चोत्तिष्ठते शब्द: सर्वलोकेश्वरात् प्रभो: | आकाशं युज्यते येन ततस्तिष्ठत्यसंवृतम्
tasmāc cottiṣṭhate śabdaḥ sarvalokeśvarāt prabhoḥ | ākāśaṃ yujyate yena tatas tiṣṭhaty asaṃvṛtam ||
因此，主啊，声音从统御一切世界的至上主宰而起。凭借那与之恒常相应的原理，虚空（ākāśa）得以维系；也正因那原理，虚空长存通达，无所障蔽，无所覆盖。

Educational Q&A
The verse presents a metaphysical claim: sound (śabda), the defining quality associated with space (ākāśa), ultimately proceeds from the Supreme Lord (sarvalokeśvara). Space remains open and unobstructed because it is sustained through that divine principle with which it is eternally connected.
Nārada is explaining a doctrinal point in the Śānti Parva’s instruction-setting: he links a basic feature of the cosmos—sound and the nature of space—to the sovereignty of the Lord, framing cosmological description as a form of theological teaching.
