I think the basic premise is that there are vibrations to the universe, both constructive, positive, and healing. and negative ones that are destructive and problematic. some people would consider prayers to be a ritualized version of the same kinda thing. so in the same general ball park, but maybe not the same game exactly.
When you feel a person is going to work out professional at work or during a personal relationship. They give off good vibes, as in you like them and you "click" with them.
