Actually later I plan to give a little talk about Dukkha, Anicca, and Anatta, and a guided meditation. Dukkha, unsatisfactoriness; Anicca, impermanence; Anatta, not-self. When things are impermanent, we begin to see that things which are impermanent cannot ultimately be called mine, Anatta, not-self. Also because things are impermanent, and not mine, unsatisfactoriness exists, Dukkha. That is a brief way to describe their relationship.
