The ego is your best friend.
Self-esteem is extremely important.
Ego only becomes a problem when it starts clouding an objective perspective. For example if you’re not very good at something and someone points that out, instead of incorporating that you call them a liar and still cling your belief that you are better than you actually are at that thing despite the evidence to the contrary.
Do not eliminate the ego. You can’t really do that anyway. Grow it, but to your benefit and in accordance to the Gods and realism.
Throw away all “dharmic”/new age/jewish concepts of “eliminating the ego”. That will only harm you.
The individual ego of yourself and collective ego of your tribe and religion is Pagan, Zevist and good for you. That is how both individuals and groups survive, thrive and conquer.
