The works of Ādi Śaṅkarācārya

Ātmabodhaḥ

Verse 18

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.
