And what that means is that you understand that suffering comes from you wanting stuff. That nothing is permanent. Everything is non-permanent. So as soon as you're like, I really want that gum, oh I need that gum, and you get the gum, then the gum's gone and you want something else. So what Buddha says is that in the second noble truth, you have to understand that your suffering originates in your mind, wanting stuff and desiring stuff. So then the third noble truth is nirodha, which means stopping the dukkha. If you can stop the dukkha, then you can create nirvana.
