As long as we focus on the outside, there will always be that empty, hungry, lost place inside that needs to be filled.
Every time you have a desire, in a certain sense you have a goal, something you would like to be, do, or have. Some desires are merely passing fancies, but others stay with us and go deeper. Our desires and our goals give us direction and focus. They help point us down our path of action in our life.
In the Western world there isn't much value given to the necessity for just being quiet. And just resting, and just being, without a focus or a goal. At least a certain amount in our lives - we don't need to do half and half; it's okay if we're doing a lot of doing, we just need some being mixed in.
