Many spiritual and psychological modalities will demonize the ego.
The ego is a necessary "body" we need to wear in order to live in and survive in the world. It can get out of hand and is the main brake on one's ascension process.
Yet it is necessary.
We can easily identify the ego when we feel a strong negative emotion. Whether fear, anger, frustration, intimidation... all these are felt by the ego.
When I trace the feelings, I often find them in one particular part of the physical body.
Next time you feel a strong negative emotion, trace it to a part in your body and then bathe it with love.
A lot of awakened masters have huge egos. This is reflected in the us/them mentality, "my way of doing things is the only way" mentality, and a huge resistance to try or learn any other "modality". They are often "healers" too, with a huge list of returning clients who "need" them.
The ego will battle and fight to survive.
Do I have an ego? Of course I do. All humans have an ego and I exist here on Earth as a human. Does it get out of hand sometimes? YES.
I can be arrogant, or feel a need to be "right", be ignorant of others feelings and outright needy at times.
And when I feel those things, I trace it back to the source and bathe it with love. Sometimes the feelings will bite me in the ass and I will do something stupid, like argue or feel hurt.
One thing though, the battles become silly and a waste of valuable time and resources. And the times of ego become smaller and less damaging, while the times of existing in Oneness become longer.
