Question

What is the key to understand suffering?

Answer 1

One of the Buddha’s key teachings — arguably the key teaching — is the four noble truths, which tell us 1) that suffering happens, 2) that it happens for a reason, which is that we cling, 3) that it’s possible for us to reach a state where we don’t suffer (nirvana), and 4) that there are practices that help us to attain that state.
