so I'll share this one. It's a bit long. The ego is the program that runs personality, the body and interactions with others on the physical plane It can be a very useful tool

The ego only becomes destructive when a person identifies the ego as her or his whole being That brings tremendous suffering because the ego is full of desires the fulfillment of which will never bring lasting happiness.

Such a person becomes trapped in time and desires. If you take the perspective of the ego, then there is suffering as the ego struggles to preserve its identity in the space of the soul's desire to merge with God.
