Apparently not much aimed; it backs off whenever she drops the chakra she's putting into it. 

Little tongues of blue-green flame start licking around it after a bit, centered on the spiral. 

Oooh. She continues pouring. Did anything else change?

The flames get thicker, and start slooowwwlyyy inching along her chakra strings.

Fascinating. What if she uses her other hand too?

The flames start licking towards her other hand, too. 

Is the illusion thing any different?

Not really. It's mostly faded out.

She'll keep at it for a bit to see whether it does anything more interesting than try to consume her with flames.

The flames start to speed up a bit. They'll be at her hand before anything else happens.

She stops and squints at it.

It's definitely agitated. The flames have gone back to swirling around the spiral; they start to calm down as she watches.

And the chakra is all just—there?

It's moving and flaring some, but it's not really doing anything, no.

If she squints long enough something like a pattern to the flares emerges - the strength of the chakra varies in a wave-like pattern, though the amplitude as frequency are slowly changing.

...and is there a pattern to how they're changing?

They're decreasing, at a fairly steady rate. The flames start to fade out after a point. 

...huh. That's interesting.

Okay now the other way around: can she draw chakra from it?

Not from a distance.

...she waits until it's cold and touches it again to try.

It's really hard. 

She eventually manages somewhat, and almost immediately gets a handful of flames - they're cool to the touch - and the surface starts heating up rapidly.

She stops immediately.

The jewel starts to calm back down, but more slowly than before.

Huh! And are the flames when she gives it chakra also cool? She'd been assuming they were hot but if it's just the surface of it that's hot...

It's hard to tell what with the jewel radiating heat, but if she starts feeding it chakra again, the flames do seem to be vaguely cool. (It heats up and the flames appear much faster than the previous time). 

The flames are enchanting, especially once they touch her. It'd be pleasant, certainly, to stare into them...

Oh yes it would. She does that.

A feeling of peacefulness settles over her mind like a curtain being drawn. The musical illusion from earlier returns, the flute louder and now joined by a gentle clacking sound. 

(She might notice that her chakra's draining faster than she was intending.)
