सदैवात्मा विशुद्धोऽपि ह्यशुद्धो भाति वै सदा ।यथैव द्विविधा रज्जुर्ज्ञानिनोऽज्ञानिनो निशि ॥ ६८ ॥
In plain words
The Ātman is spotless, always — and always it looks stained. Just like a rope at night: one rope, two kinds of thing, depending on whether the person looking knows what it is.
Close to the Sanskrit
Always indeed the Self, though thoroughly pure, verily appears impure always — just exactly as the rope is of two kinds at night, for the knower and for the ignorant.
