Bhagavad Gita 3.17

यस्त्वात्मरतिरेव स्यादात्मतृप्तश्च मानवः।आत्मन्येव च सन्तुष्टस्तस्य कार्यं न विद्यते॥

yastvātmaratireva syādātmatṛptaśca mānavaḥ |ātmanyeva ca santuṣṭastasya kāryaṃ na vidyate ||

But for that man who rejoices only in the Self, who is satisfied with the Self and is content in the Self alone, indeed there is nothing to do.

On the other hand, the soul who meditates on the Self is content to serve the Self and rests satisfied in the Self; there is nothing more for them to accomplish.

Our plain-language meaning of this verse is waiting for scholar review.
