indriyair indriyārtheṣu guṇair api guṇeṣu ca gṛhyamāṇeṣv ahaṁ kuryān na vidvān yas tv avikriyaḥ

This verse teaches that actions occur through the senses and the modes of nature, and the truly wise person does not identify as the doer—remaining steady as the unchanging self.

Do your duties responsibly, but mentally offer results to the Lord and drop the ego-thought “I alone am the controller,” recognizing that body, mind, and circumstances move under nature’s modes.
