Bhagavad Gita · Chapter 3: The Path of Action

Bhagavad Gita 3.17

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

But for the person who delights only in the self, who is satisfied with the self and content in the self alone, there is nothing that must be done.

Modern context

There is one exception to the rule of duty: the person who is completely fulfilled within, who seeks nothing from the world. For them nothing remains that they must do, because duty exists to bring us to that fullness. The verse describes a rare end-point. It is not a loophole for those who would simply like to be excused.
