Turning negative vibes into positive energy

Like the alchemist turns lead into gold, I'd love to be able to transmute negative pain into positive energy. To be truthful, I'm looking for a method or a way, because I sense that there must be one, and the only one I've heard about is one that is related to yoga practice.

It consists of acknowledging pain instead of denying it or pushing it back. Instead, it requires that we fully breath-in that pain, thinking that it's part of the all the pain and suffering that is plaguing the world.

Once this is done, literally exhale that same pain and focus on its leaving your own body and the entire world. I kind of like this approach and next time I'm bothered with negative vibes, I will try it!
