ŚVETĀŚVATARA UPANISHAD · 1.1

ओं ब्रह्मवादिनो वदन्ति ।

किंकारणं ब्रह्म कुतः स्म जाता जीवामः केन क्व च संप्रतिष्ठाः ।
अधिष्ठिताः केन सुखेतरेषु वर्तामहे ब्रह्मविदो व्यवस्थाम् ॥

oṃ brahmavādino vadanti ।

kiṃkāraṇaṃ brahma kutaḥ sma jātā jīvāmaḥ kena kva ca saṃpratiṣṭhāḥ ।
adhiṣṭhitāḥ kena sukhetareṣu vartāmahe brahmavido vyavasthām ॥

The Brahma-students say: Is Brahman the cause? Whence are we born? Whereby do we live, and whither do we go? O ye who know Brahman, (tell us) at whose command we abide, whether in pain or in pleasure?
