Jason Silva’s latest short video, a bittersweet meditation on transience:

Everything changes. Motion is constant. You never step into the same river twice. This moment is gone already.

How do we live with impermanence? How do we make sense of knowing that we are unique, once in a universe creatures who will be gone soon? All that we love and hold dear will escape our grasp.

I was at my aunt’s funeral last week. Our family has lost her, but the universe keeps spinning. We have memories of happy times and moments shared, and we have the sadness that we will not look her in the eyes ever again. And all of us know that one day we will be the ones that our family and friends mourn.

What a world.

We are the only animals that live in the light of our own mortality. Yet we also are the only ones who can experience the awe of just being alive.

Do not go gentle into that good night. Rage, rage against the dying of the light. -Dylan Thomas
