I can imagine that there is an alternate realm of existence where all states of energy do not vibrate or solidify into form.

In that place, all is Sustainable, because all is static.

But that is not the reality we find ourselves in. Where we live, all is vibrating, forming, becoming, stopping, decaying, undoing, restarting, reforming, reemerging, vibrating, forming, becoming...

Creation and chaos.

Order and disorder.

The creation of order being chaotic to the disorder, and visa versa. It’s a system of circular entropy.

Energy in all its forms is constantly engaged in a grand game of musical chairs, sloshing around from one state to another and back again.

Even the simplest breath takes its own hero’s journey, a cycle of fall and pause and rise and pause and fall and reiteration spiraling out, and each of those falls/pauses/rises/pauses has it's own cycle of fall, pause, rise, pause, and in turn each of those falls/pauses/rises/pauses has it's own series of iterative subdivisions.

So what is Sustainable here, then, if all is subject to the inevitability of change?

The asking of the question generates the answer: change. 

As an inevitability, it Sustains.

I can imagine that there is an alternate realm of existence where all states of energy vibrate and solidify into form.

In that place, all is Sustainable, because none is static.
