पूर्णात्मानात्मभेदात्त्रिविधमिह परं बुद्ध्यवच्छिन्नमन्य -त्तत्रैवाभासमात्रं गगनमिव जले त्रिप्रकारं विभाति ।अम्भोवच्छिन्नमस्मिन्प्रतिफलितमतः पाथसोऽन्तर्बहिश्चपूर्णावच्छिन्नयोगे व्रजति लयमविद्या स्वकार्यैः सहैव ॥ ५४ ॥
In plain words
Once full Ātma is distinguished from Anātma, what is not the Self, reality can be seen as unbounded, as seemingly enclosed by Buddhi, and as a reflection within that intellect—like open space, space bounded by water and space mirrored on its surface. When the bounded is known as one with the Full, Avidyā, fundamental ignorance, and everything born from it come to an end.
Close to the Sanskrit
Through the distinction between the full Ātma and Anātma, the non-self, the supreme reality appears here in three ways: as the Full, as delimited by Buddhi, and there as mere reflection—like space appearing threefold in relation to water. Space is seen as delimited by water, reflected in it, and present both within and beyond it. When the full and delimited are joined as one, Avidyā dissolves together with all its effects.
