If you focus on the issue of suffering, a lot of things are brought right there together. Because right where there’s feeling there’s also attention and intention, perception — particularly intention. And when these issues are solved, everything important gets solved as well.
"The Buddha started and ended his teaching with the issue of how to put an end to suffering, and it’s easy to agree with him that this is an important issue to address. Some people, though, wonder if that’s all he addresses. Just put an end to suffering? What else is there? Aren’t there bigger issues in life? Actually, it was a part of the Buddha’s genius to realize that if you put an end to suffering, you learn a lot of other things about the mind. If you focus on the issue of suffering, a lot of things are brought right there together. Because right where there’s feeling there’s also attention and intention, perception — particularly intention. And when these issues are solved, everything important gets solved as well." ~ Thanissaro Bhikkhu "The Choice Not to Suffer"
