Ego and Extreme Ego are often wrongly described as if they were the same. Though they do evolve from one another, anything extreme is unnatural and has the ability to considerably affect the vibration of those it touches in a negative way.
For instance, if you are accused of being sneaky, your Ego might dislike the person confronting you. If Extreme Ego is involved, you could feel a strong hate towards them. At times, you may even feel your body trembling to contain its response.
