karmaṇyakarma yaḥ paśhyed akarmaṇi cha karma yaḥ
sa buddhimān manuṣhyeṣhu sa yuktaḥ kṛitsna-karma-kṛit||18||

Meaning : True wisdom is seeing beyond the obvious — knowing that even when you seem inactive, some action is happening, and when you act, sometimes it can be like inaction. One who realizes this subtle truth is steady-minded and balanced in all activities, untouched by the binding effects of karma.
