all conditioned phenomena are dukkha.
It is not seeing this, to think that there can be true happiness (that lasts forever) in the world it is referred to in the sutta quoted as seeing pleasure in the stressful. That’s the meaning.
There’s no denying that there’s happiness (temporary) in the world. But because they are temporary, that’s why they are dukkha of change and dukkha of conditionality. Don’t just limit dukkha to unpleasant feelings, like you do with the post above. Or else you’re just ignoring Sn45.165.
Of course, to beginners who cannot see dukkha also includes unsatisfactoriness, we have to be careful to not lead them to become depressed. But you’re no longer a beginner. And the post I made about the 3 types of suffering is very clear and based on SN45.165. One has to go deeper into the teaching to understand the dhamma well.
Yes, as mentioned by others above, any experience is dukkha, at least for the dukkha of change and conditionality. Just think of unsatisfactoriness, not unpleasant feelings suffering.
Only true for sukha is not dukkha dukkha, or unpleasant feeling suffering. But sukha is dukkha of change and dukkha of conditionality. It is unsatisfactory because it is impermanent and conditioned. One has to see this deeply to be able to let go of even all happiness in the world. (Or see impermanence or no-self)
Suffering. Unsatisfactoriness perhaps is the better translation.
