ŚVETĀŚVATARA UPANISHAD · 3.17
सर्वेन्द्रियगुणाभासं सर्वेन्द्रियविवर्जितं ।
सर्वस्य प्रभुम् ईशानं सर्वस्य शरणं सुहृत् ॥
sarvendriyaguṇābhāsaṃ sarvendriyavivarjitaṃ ।
sarvasya prabhum īśānaṃ sarvasya śaraṇaṃ suhṛt ॥
Separate from all the senses, yet reflecting the qualities of all the senses, it is the lord and ruler of all, it is the great refuge of all.
F. Max Müller · The Upanishads, Sacred Books of the East 15 (1884)
