Rest does not come with sleeping, it comes with waking. This is both an insight and an action of enlightenment. When we are enlightened we realise that real rest is possible only when we become free of illusion and we no longer struggle against life.
Illusion is the idea that people should be, and do, what we want them to. The truth is, all is as it should be, despite appearances, or our perceptions of others to the contrary. This means you can be easy on yourself, easy with others and easy with the world around you.
Easiness is a virtue, an attractive one at that. It is much more influential than force. So quit forcing, end the struggling and...relax!
