If you go into a room where someone's been having a big argument, it's not so pleasant. You can feel it. Even if the argument's over, you can feel it. But if you go into a room where someone has just finished meditating, you can feel that bliss. It's very nice to feel that.
We all affect our environments. You enjoy that light inside, and if you ramp it up brighter and brighter, you enjoy more and more of it. And that light will extend out farther and farther.
