Yeah he's-- okay, he hasn't really explained it in detail to me, but what I assume he's doing is using his own chakra to force closed specific chakra nodes in my body. Like pressure points-- they just get cut off from my chakra circulation.

The healing I can do is the same basic principle-- pushing my chakra into another person's body -- but obviously we manipulate it differently, and with different effect. If I were really good at it though, I could put somebody into a coma by pushing enough of my energy into them. That's why control is so important.
