Tohu va bohu is a Hebrew phrase that means confusion or chaos. It comes from the creation story in the Bible when God created the world. Before God created the world, there was nothing but emptiness and darkness. This is called tohu va bohu because it was a chaotic and confused state of nothingness.
Imagine you have a big box of toys and have dumped them all out onto the floor. The toys are scattered all over the place. It's hard to find what you're looking for because everything is mixed up and chaotic. That's like tohu va bohu because everything is confused and disordered.
But just like you can organize your toys and put them away neatly, God brought order and created the world by separating the light from the darkness, the waters from the land, and creating all the living things. So when we say tohu va bohu, we are describing something that is chaotic and disordered, but we can also remember that order can be brought out of chaos.
