You start out as an infant with undifferentiated awareness, and then you are taught who you are by someone who isn’t you.
How would they know who you are? Your impressions of their opinion of who you are forms your ego. A set of habits three times removed from reality.
You’re essentially tricked into thinking your ego is who you are and that fallacy and disconnect from reality is the seedbed of suffering.
Freedom is achieved through dropping the ego and rediscovering your undifferentiated self.
“For the Kingdom of Heaven belongs to those who are like these children.” (Matt 19:14)
