The idea of unlearning resonates with me. I think it's ego that propels us to hold onto everything that we identify as "us", which includes "our" knowledge. Since it's already "ours", it becomes difficult for us to simply drop it because that would mean admitting part of us is wrong which is painful. We do not pay enough attention to be aware that this is going on when we encounter new knowledge. This mindset is very detrimental. I feel this because the proximity with my mother allows me to observe her fierce resistance when anyone tries to tell her something new, something against her existing beliefs. It's like death to her. And the conversation usually ends in despair for both parties for the wall she puts up in front of her prevents a transformation from happening, a strengthened connection from building. It's very disheartening to see her remaining as an old baby in her journey of life. Let's let our ego die a bit, in the context of learning and acquiring knowledge.
