The Gita distinguishes between the 'Lower Ego' (which is attached to labels and titles) and the 'Higher Self'. Transcendence of the ego is the prerequisite for peace.
The ego-deluded person thinks 'I am the doer' while all actions are performed by the modes of nature.
If you are conscious of Me, you will pass over all obstacles; but if you act through ego, you will be lost.
A CEO who takes all the credit for a company's success is acting through ego. A Sattvic leader recognizes the contribution of their team and the favorable circumstances, remaining humble.
