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. And that means once you've reached nirvana, you don't have to keep coming back to this miserable place. Because the idea is when you want something, when you need something, that creates karma. And that karma is what keeps you trapped in this reincarnation cycle.
