Attachment to the Eight worldly dhammas, whether it's a positive one or a negative one, is always going to bring us pain. It's not the Eight worldly dhammas that's going to bring us pain, it's our attachment to them, positive or negative. Everybody on the planet gets these Eight to some degree if they live long enough. The Buddha got all Eight. He got the praise, he also got the blame. He got the gain; he also got the loss, and so on. But, supposedly he wasn't attached to any of them. So the more we can lessen our attachment, using any wise thoughts at all, understanding that they are impermanent, understanding that, even though someone praises you, it doesn't always mean much. It depends on who is praising you as to the quality of the praise. To understand that, say with praise and blame in particular, they don't change your basic Kamma.
Imagine that you have done something very good, very beneficial, and somebody praises you. Does that change your Kamma, make it any better or any worse? Say you have done something very good and someone blames you? Does that change your Kamma? Say you have done something not good and someone blames you? Does that change your Kamma? Say you have done something very bad and someone praises you? Does that change your Kamma?
It doesn't. None of these reactions of other people will change your Kamma. While if you have done something good, then that's a good Kammic event, if you have done something not good that's not a good Kammic event. It won't change based on others' praise or blame.
However, let's say you did something good, and somebody praises you, and you go, "Yeah!" Does that change your Kamma? Let's say you do something good and somebody blames you, and you get angry. Does that change your Kamma? Let's say you do something bad and somebody blames you, and you get angry. Does that change your Kamma? Let's say you do something bad and someone praises you! And you feel happy! Does that change your Kamma?
It's going to be your reaction to the praise or blame, it will be your reaction to the fame and obscurity and all the others. It's always going to be your reaction, whether you actually change your Kamma or not. So reflecting on that way is very helpful.
Can I prevent them coming or make them come? That's another wise thought. As far as the Eight worldly dhammas go, we can't prevent them coming to a certain extent. I mean, if you want to be sure that you don't get fame, fine, go hide away somewhere. But invariably you have to come out of there and go shopping, and somebody will look at you and think, "That's that weirdo who lives in the woods!" You get your fame no matter what! Even hiding away in the woods, you are going to be famous. So, as far as preventing getting any of them to a certain extent, maybe yes or no, but quite frankly, if we prevent our attachment to that, that's the biggest thing.
