From the seven hundred
न हि कश्चित्क्षणमपि जातु तिष्ठत्यकर्मकृत्कार्यते ह्यवशः कर्म सर्वः प्रकृतिजैर्गुणैः
na hi kaścit kṣaṇam api jātu tiṣṭhaty akarmakṛt kāryate hy avaśaḥ karma sarvaḥ prakṛti-jair guṇaiḥ

“No one can stay still for even a moment without acting. Everyone is driven to act, helplessly, by the forces of their own nature.”

Bhagavad Gita 3.5
In plain terms

Opting out is off the menu. Even sitting perfectly still, the body breathes, the mind churns, the day acts through you. Everyone is in motion all the time, driven by their own nature.

So the real question shifts from whether to act to how. Since action cannot be avoided, the Gita turns its whole attention to the spirit it is done in.
