Śvetāśvatara Upaniṣad · 6..11
एको देवः सर्वभूतेषु गूढः सर्वव्यापी सर्वभूतान्तरात्मा | कर्माध्यक्षः सर्वभूताधिवासः साक्षी चेता केवलो निर्गुणश्च
eko devaḥ sarvabhūteṣu gūḍhaḥ sarvavyāpī sarvabhūtāntarātmā | karmādhyakṣaḥ sarvabhūtādhivāsaḥ sākṣī cetā kevalo nirguṇaś ca
One God, hidden in all beings, all-pervading, the inner Self of all beings, overseer of actions, dwelling in all beings, witness, pure consciousness, alone, without attributes.
A verse that synthesizes the theology of this Upaniṣad:
Eko devaḥ — One God. Upaniṣadic monotheism.
Sarvabhūteṣu gūḍhaḥ — Hidden in all beings. Not absent but veiled.
Sarvavyāpī — All-pervading, present in everything.
Sarvabhūtāntarātmā — The inner Self (antarātmā) of all beings.
Karmādhyakṣaḥ — Overseer of actions. Witness and regulator of karma.
Sarvabhūtādhivāsaḥ — Dwelling in all beings. All exist in Him.
Sākṣī — Witness. Observer without participating.
Cetā — Pure consciousness.
Kevala — Alone, absolute, without a second.
Nirguṇa — Without attributes. Beyond all qualification.
The apparent contradiction between nirguṇa (without attributes) and the attributes listed reflects the Upaniṣadic dialectic: Brahman transcends attributes but can be described provisionally to guide understanding.
