As far as I understand, suffering is conditioned to the fact, that we always want to keep "good feelings".
When a good feeling ends, we want to experience this or another good feeling, again and we try to "get" it.
The "hunger" for the good feelings means in my understanding to suffer.
The ceasing of the will means in my understanding to get free of suffering.
Well......it's difficult to find the words in my native language, I really hope I wrote comprehentible.
Many greetings from
