personally, i see no problem with "swooshing." leaving a large amount of energy in one place can sometimes cause an imbalance. it can have its uses though, depending on what you're doing. but for the most part, i think it more important that one have clear channels than large maounts of energy flowing through them. if a patient needs more energy afte ryou clear it out of them, just give them some water or tea afterwards. it grounds them, and provides them with jing. if someone needs energy, the universe will provide whther they actively intake it or not. when someone gets attuned, what's important is taht their pathways are cleared, not that they are given alot of energy (mainly anyway....certain attunements can be energy intensive, but that's the basic philosophy, right?). swoosh all you like, if intent is to clear away negative energy, than that's what will happen.
