Obviously, his casual act of momentary spite from across the galaxy is still pretty nasty. 

Mostly it's just the deafening static noise in her head and a feeling like she's starting to come apart, it's not very clear what's around her, but she - 

- nods -

Yoda never taught him anything like this. He knows a strong-minded person can't be deceived by the Force and simply going harder risks horrific damage, but nothing quite like this. 

...He just reaches into the Force and grabs at the dark pulsing thing and pulls firmly. 

There's a sickening twisting feeling of something that isn't quite the same as agonising physical pain - 

- and then a deep, deep kind of warmth, like sitting just slightly too close to a fire so it's just on the edge of too much. 

Three are the stones of my hearth; thirteen are its coals.
I seize you by the neck. I burn the red binding of her heart, the white binding of her breath, the black binding of her hand, the yellow binding of her sleep.

*cleansing flames start to spark on the curse, and also on Mara's memories and current drug stack, whoops?*

All right, he reaches out again and this time puts some real power into lifting it free. 

Ah, like doing surgery with a power saw. Impressive and hilariously messy. Maybe he will go for another Skywalker apprentice.  

She slumps suddenly - 

Something that is not the Force kindles inside her mind and -

- she's sober, which is to say in agony and totally unable to string a thought together -

- she wasn't that young when the Emperor took her, she remembers now. There was an imperial facility, that makes sense. Her parents hadn't wanted her to go and she hadn't wanted to either and then the Emperor smiled at her and she knew she was going with him and then he waved a hand and everyone else in the room died and she forgot - most of her young life -

This is in fact not something a human mind is designed to do. 

He flings the captive darkness away into the void at once and catches her body before it hits the ground and the light of her mind before - something - 

His voice is completely calm. 

"Chuk, do you know what's happening?"

"Keep chanting. It is dangerous to stop midway"

I mean I do it, but I'm me.

You are flung to the east: you are not received. To the north: you are not received. To the south: you are not received. To the west: you are not received, and your father will not have you back.
You have no tree. You have no bird. Your word is ash.
Thirteen are the jars of my cold water. I cool the red ember, the white ember, the black ember, the yellow ember. I cool her heart, her breath, her hand, her sleep.
What was his is burnt. What is hers is left to her.
Hun Ahau. Can Ahau. Urgently, urgently, as the Bacabs and the Way command.

Yoda had mentioned that the Force could be used for healing, but it is difficult, dangerous, highly restricted... well. He gestures and settles her body back into the chair, and waits for Chuk to finish. 

"I gotcha. Is there a bed?"
