ŚVETĀŚVATARA UPANISHAD · 6.11

एको देवः सर्वभूतेषु गूढः सर्वव्यापी सर्वभूतान्तरात्मा ।
कर्माध्यक्षः सर्वभूताधिवासः साक्षी चेता केवलो निर्गुणश् च ॥

eko devaḥ sarvabhūteṣu gūḍhaḥ sarvavyāpī sarvabhūtāntarātmā ।

He is the one God, hidden in all beings, all-pervading, the self within all beings, watching over all works, dwelling in all beings, the witness, the perceiver, the only one, free from qualities.
