Is the confidence I feel while doing bhajan ego or self-belief?
How to recognise real ego
Ego shows when you take pride in your own qualities, look for faults in others, and use your strength to defeat or belittle them. The ego of "I am constantly remembering the Lord" is soft: it bows before everyone and stays humble.
Pride in one's own qualities, seeing faults in others, and using one's own strength to defeat and belittle others: this is what is called ego.
