ŚVETĀŚVATARA UPANISHAD · 1.3

ते ध्यानयोगानुगता अपश्यन् देवात्मशक्तिं स्वगुणैर् निगूढाम् ।
यः कारणानि निखिलानि तानि कालात्मयुक्तान्य् अधितिष्ठत्य् एकः ॥

te dhyānayogānugatā apaśyan devātmaśaktiṃ svaguṇair nigūḍhām ।
yaḥ kāraṇāni nikhilāni tāni kālātmayuktāny adhitiṣṭhaty ekaḥ ॥

The sages, devoted to meditation and concentration, have seen the power belonging to God himself, hidden in its own qualities (guna). He, being one, superintends all those causes, time, self, and the rest.
