सदा सर्वगतोऽप्यात्मा न सर्वत्रावभासते ।बुद्धावेवावभासेत स्वच्छेषु प्रतिबिम्बवत् ॥ १७ ॥
In plain words
The ātman is everywhere, always — and still it does not show itself everywhere. It shines in the intellect alone, the way a reflection appears only in what is clear.
Close to the Sanskrit
Though the Self is always all-pervading, it does not shine forth everywhere; it shines in the intellect alone, like a reflection in clear surfaces.
