The Sefirot are a map of the structure of existence. The first one, which all the other ones come from, is Ratzon, which means desire. Ratzon is like the spiritual big bang. It's the first thing that, when it came into existence, the whole universe and all the worlds in it did. And what that means is that when God wanted to exist, the world was created.
In "On Liking Women," Andrea Long Chu talks about how transition is so much about desire and about wanting things. What I'm doing as a trans person is committing to desire. And Kabbalistically, that means something really specific and really amazing.
By letting my desire create me, instead of my identity, I am in sync with the entire universe which is created not by what it is but by the will of God. So the next time dysphoria tries to tell you that you're not real, you tell dysphoria that there is no existence except through desire and that our pursuit of that yearning is what makes us sacred.
