सम्यग्विज्ञानवान् योगी स्वात्मन्येवाखिलं जगत् ।एकं च सर्वमात्मानमीक्षते ज्ञानचक्षुषा ॥ ४७ ॥
In plain words
The yogi in whom knowledge has fully arrived sees the whole world inside his own Self — there, and nowhere else. With the eye of knowledge he sees the Self as one, and that one as everything.
Close to the Sanskrit
