“If you let go a little, you’ll have a little happiness. If you let go a lot, you’ll have a lot of happiness. If you let go completely . . . you’ll be completely happy.” - Achaan Chah
The Third Noble Truth, the end of suffering, is a very positive message in Buddhism and tells us that suffering can be overcome and happiness can be found for anyone.
The First Noble Truth reminded us that because everything is impermanent and always changing there is suffering, dissatisfaction and unreliability in life; there just is. Accepting that truth we looked to the Second Noble Truth that told us that craving causes suffering; we get attached to and crave all kinds of impermanent things hoping they will stabilize our experience in the world and make us happy. But, pretty soon, we realize things don’t live up to their promise, they can't, they don't last. So, we begin to put it together that suffering and the causes of suffering depend on our own states of mind and on our own views about what’s going on, not on the things we desire.
The good news, the reassuring news from Third Noble Truth is the fact anyone can change their mind states and their views and know happiness and contentment now. We do this by seeing through and letting go of the misperceptions and delusions we've constructed to support how we want things to be in favor of a natural alignment with how things actually are. The extent to which we let go of our craving is the extent to which suffering will drop away.
