If you can bite, you generally don't have to. - Jordan Peterson

You want to have a meaningful life? Everything you do matters. That's the definition of a meaningful life. But everything you do matters. So you're going to have to carry that with you.

What is the moral of the story? Make yourself colorful, stand out, and the lions will take you down. And the lions are always there.

The lion lying down with the lamb is the idea that is either projected back in time, saying that there was a time, or maybe that there will be a time, when the horrors of life are no longer necessary for life itself to exist. And the horrors of life are, of course, that everything eats everything else, and that everything dies, and that everything is born, and that the whole place is a charnel house. It's a catastrophe from beginning to end.
This is the vision of it being other than that. There's a strong idea that human beings can interact with reality in such a way that the tragic and evil elements of it can be mitigated, so that we can move closer to a state of being where we have the benefits of existence without the catastrophe that seems to go along with it.
