Even while faced with the truth that I am experiencing pain at this moment in time, I also immediately recognize that there are times when I do not hurt. At the very least, I can remember moments of bliss and utter freedom. In this very moment, even, I may get a brief glimpse of this freedom, especially if I have recognized very clearly what is causing my pain.
Perhaps the most important and noble truth of all: Pain and suffering ends. There is an end to it. If I have ever in my life known a moment of genuine happiness, this is proof of that fact. Though life as we know it includes pain and suffering, the fact that we know moments without it tells us that pain ends and joy exists.
The fact of joy is the third important truth.
