भानोरन्य इवाभाति जलभानुर्जले यथा ।आत्मनोऽन्य इवाभासो भाति बुद्धौ तथात्मनः ॥ ५३ ॥
In plain words
Look at the sun's image lying in water: it shines there as though it were some second sun of its own. In just that way the ātman's reflection shines in the intellect, as though it were someone other than the ātman.
Close to the Sanskrit
Just as the water-sun in the water shines forth as if other than the sun, so the reflection of the Self shines in the intellect as if other than the Self.
