Well, Yoda's ESB description of the Force seems to fit. 'Life creates it, makes it grow' and so forth. So Leia using all of her own life force and everything it could channel goes right along with that concept.

Also, the way she envisions the chain digging into him is an analogue to what Luke says in his training in the first movie: 'You know, I did feel something--I could almost see the remote.' To me at least, not only does this pertain to being able to "see" without looking, but also envisioning what you want to happen and then bringing it about, consciously or otherwise. Leia, of course, does not know that she is using the Force, but in making such effort causes it comes to her aid when she has real need of it, I suppose.

The similarities are far too great far it to be a coincidence that he chose to describe Jabba's death this way.
