That is the one sentence I would say is the key lesson that young souls need to learn.
From my observation of society this is the one key identifier- immature souls are the ones who shut their ears to others if it disagrees with their viewpoint completely closing themselves to the fact there are inifinite more possibilities than one. Immature souls see the world through "their eyes" and that is the only world that is actually valid and exists.
I just sigh and think I would love to live long enough to observe the maturation process of their souls and the character evolution that comes along with that knowledge and awareness gained.
I guess, in a way, I am just completely jealous of young souls...as we all know, Ignorance is Bliss! They always have that innate natural gift of just being able to enjoy the moment and have no concern for consequences of actions, the past or the future. Most of us actually have to consciously learn to live in the present and most of us are burdened from worrying about the consequences of our actions, the past and the future, probably too much.
