I was thinking about this earlier: That a child is like watching Buddha. They are born as enlightents beings, and then build walls as you wrote. Walls also build inside our heads, but that are merely illusions. I was feeling quite anxious the other day and I said to myself: What would a child do/think of this situation. I felt better immediately. Thanks for sharing!
Sometimes we need to step out of the problem in order to see that it's much smaller than we actually believed...:-)
Have a great weekend!
