बाह्यानित्यसुखासक्तिं हित्वात्मसुखनिर्वृतः ।घटस्थदीपवत्स्वस्थः स्वान्तरेव प्रकाशते ॥ ५१ ॥
In plain words
He lets go of his grip on outer pleasures — the ones that arrive and leave — and rests, satisfied, in the bliss of the Self. Like a lamp set inside a clay pot, he stands in himself and shines nowhere but within.
Close to the Sanskrit
Having abandoned attachment to external, impermanent pleasure, content in the bliss of the Self, standing in himself like a lamp set inside a pot, he shines within himself alone.
