Yeah, that gives me an idea. Since Ninshu connects people together, Senkai's mastery over it's teachings could've affected him in addition to the Senjutsu, in a way that it literally "connected" his other energies to that of natural energy permanently. Ninshuu around here has barely been focused on (exceptions being Sei and Ten). And it would explain the "permanently connected" stuff.
