यस्त्वात्मरतिरेव स्यादात्मतृप्तश्च मानवः। आत्मन्येव च सन्तुष्टस्तस्य कार्यं न विद्यते॥
yastvātmaratireva syādātmatṛptaśca mānavaḥ ātmanyeva ca santuṣṭastasya kāryaṃ na vidyate
Meaning
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.
