Spirit Bending

Spiritbending is a variation of the healing technique which allows the user to instill a balance or an imbalance within spirits. It was invented by Unalaq,[9] who successfully taught it to Korra.[10] To perform the technique, a waterbender encircles the spirit with a thin stream of water, which begins to glow when the technique is taking effect. When used to change a spirit's negative energy into positive energy, the water, followed by the spirit, will begin to glow a golden light, at which point the spirit dissipates or assumes a pacified form. When the technique is used to change positive energy into negative energy, the water and spirit emanate a purple light. When used against humans, this variation has the potential to destroy their souls.[11]
