Throughout this forum, there are many members expressing opinions about ego. But I cannot comprehend what they're explaining.  I want to know what ego is. So, I searched for the word ego and learned this:  My takeaway from these definitions is that ego is pretty much an opinion you have about yourself. For example, you drive a nice $70,000+ car. Thereafter, you're mentally expressing to yourself how good/better you are. Is this right?  What gets me confused is how people talk about killing ego, an ego is nothing, reality this, meditation that and so on.  In short, I want to gain the knowledge about what is an "ego." Can someone explain it here - in this thread - articulately that a 10 year old can comprehend? Thank you.
