देहेन्द्रियमनोबुद्धिप्रकृतिभ्यो विलक्षणम् ।तद्वृत्तिसाक्षिणं विद्यादात्मानं राजवत्सदा ॥ १८ ॥
In plain words
Not the body, not the senses, not the mind, not the intellect, not even prakṛti — the Self is other than all of them, and it watches everything they do. Know it that way, always: as a king.
Close to the Sanskrit
Distinct from body, senses, mind, intellect, and prakṛti; the witness of their modifications — one should know the Self, like a king, always.
