Understanding why there is suffering is different than understanding what suffering is. Why suffering exists and what it is both spring from the same misunderstanding, however. We think that the every day reality in which we all live is the only one. We think that we have an “I”, a “self” which is different from our imperishable natures. We think that getting whatever the self wants and thinks is good will make us happy, and that getting things the self thinks are undesirable and bad will make us unhappy, but that isn’t true. It makes us grasp at the things we want, and that grasping doesn’t just lead to suffering, but it is suffering. The key to understanding suffering is that if you were to be without it, you would neither want certain things, shun other things, nor be indifferent to anything, either.
