I think I read it in Helen MacDonald's book... a human hand is meant to hold another hand... we are social beings, made to share our lives... together...
There are the "dividers," the "judges" those who will try to form hierarchies, and form those little clubs of "us against them."
But we are human beings first... made to be in community with other human beings. Sometimes that comes through loud and clear. And when it does it is uplifting, enlightening, healing.
How do you hold onto that feeling, that overwhelming sense always, every day, every moment? Don't know. But it's something worth trying to do.
