Giving and receiving energy

[sausagehead]

I watched this video where this guy talks about how putting energy into the universe is how you receive from the universe. Essentially the more action you take the more the world gives back. I mean it sounds like common sense on a practically level (nothing just happens on its own) but it also seems true on a deeper more universal level. Is there any teachers or books that talk about the importance of putting energy into the universe?
