PrU 4.1
अथ हैनं सौर्यायणी गार्ग्यः पप्रच्छ । भगवन्न् एतस्मिन् पुरुषे कानि स्वपन्ति । कान्य् अस्मिञ् जाग्रति । कतर एष देवः स्वप्नान् पश्यति । कस्यैतत् सुखं भवति । कस्मिन् नु सर्वे संप्रतिष्ठिता भवन्तीति
atha hainaṃ sauryāyaṇī gārgyaḥ papraccha | bhagavann etasmin puruṣe kāni svapanti | kāny asmiñ jāgrati | katara eṣa devaḥ svapnān paśyati | kasyaitat sukhaṃ bhavati | kasmin nu sarve saṃpratiṣṭhitā bhavantīti
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Then Sauryâyanin Gârgya asked: "Sir, What are they that sleep in this man, and what are they that are awake in him? What power (deva) is it that sees dreams? Whose is the happiness? On what do all these depend?"
