You are perfect the way you are, and you need a little work.
~ Suzuki Roshi
I wondered about this Ponderosa pine stub. Usually when a tree hollows out, often by a lightning strike, it shows a scar on the outside, where the cambium layer has been breached. Here, the outside layer of the tree was perfect, but the center heartwood was missing.
What would it mean to be a person without a heart, standing tall, but dead inside like this tree, lacking a heart? I hope to never find out.
