A lamp, the eye that views by the light of that lamp, and the visible form that is viewed are all basically nondifferent from the element fire. In the same way, intelligence, the senses and sense perceptions have no existence separate from the supreme reality, although that Absolute Truth remains totally distinct from them.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
दीपश्चक्षुश्च रूपं च ज्योतिषो न पृथग्भवेत् । एवं धीः खानि मात्राश्च न स्युरन्यतमादृतात्
dīpaścakṣuśca rūpaṃ ca jyotiṣo na pṛthagbhavet | evaṃ dhīḥ khāni mātrāśca na syuranyatamādṛtāt
