This talk by Sharon Allen is the second in the speaker series entitled "Doorways to Insight." Sharon talks about unsatisfactoriness, which is one of three characteristics of experience. The Pali term for unsatisfactoriness, or suffering, is dukkha. Some examples of dukkha are physical pain, mental stress, sorrow, and despair. It is caused by clinging to things that will change, and/or wanting things to be other than the way they are. It can be liberating to recognize dukkha for what it is.
