As skill increases,
afflictions decrease.

Sitting in Chan is like being a horse trainer or a monkey trainer. It is not easy. Although it is not easy, we still have to sit regardless of how difficult it is. In this world, whatever you want to do is not easy and requires a lot of effort. Chan sitting is also like that. It requires a good deal of hard work and effort. If we could restrain our mad mind and calm our wild nature, and if we could confine ignorance and false thoughts to a single location, then our skill would increase day-by-day and our afflictions would decrease correspondingly.
