I sat on a stone bench for a few minutes. And when i rose I noticed that the bench had left an impression on me.

You see, this is the way of the world. We are all influencing each other. And it isn't just people. It is the everything of the everything. It is one big network of threads that leaves impressions on each other.

We (things included) are all working toward a something.

And there is something important to think about when considering the influence of things. There are forces at work that leave bad impressions. You must do your best to see and understand them. Don't allow them to change you in ways that are not pure and good.
