It is really very simple
The material on this site may seem complex, but it is really quite simple. The basic idea is that how we hold ourself is how we will live and be. Ordinarily we are caught in a kind of struggle with life. We want things to stay when they will eventually go. We want things to go but they stay. There are good times, but those are always impermanent. Because we hold on to this struggle, we feel pain, loss and morbid sadness. But if we align with a sense of health, things work as they should. We may get over our problem, or we may find a better way to work with it, or we may work through the karma of the problem so that eventually we are free. It is that simple.
