Containers represent distinctions.
The only thing that a container does, regardless of shape or representation, is to hold things.
Thingness is a kind of illusion of scale and velocity. When a bunch of energy is held tightly together and when our instruments for observation are too blunt and slow then the energy appears stationary or solid--appears to us to be a thing. We loose the aliveness that always is going on. Things seem dead only because we cannot see at the needed resolution and rate of observation.
