<div class="quote"><i>and how do you know that korra wasn't in the avatar state when Aang restored her bending? All the other avatar spirits were in the avatar state and korra's eyes were closed while it happened but when she opened them she appeared to be in the avatar state. Plus, when she restored lin beifong's bending she was in the avatar state and since you say that being in the avatar state somehow helps with energybending but isn't necessary then how do you think it helps and why do you think that?</i></div>
<p>The white glow in Aang's tattoos is different than the red-orange energy of Ozai and the blue energy of Aang. When Aang's blue energy comes out, that represents his spirit trying to bend Ozai's energy, the red-orange light. It shows that both Aang's spirit and the Avatar State (Raava's energy) are working together, but it is Aang's energy that is used first in energybending. By extension, Korra's spirit is needed when she bends energy.
</p><p>When Aang takes Yakone's bending, it can be assumed the energy battle plays out similarly to Aang vs. Ozai, even when their energies are unseen. I'm saying Raava's energy still comes out through Aang to support his energybending, not just to counter bloodbending. I assume that energybending in the Avatar State would have the same effect for other bending: its power would increase greatly.
</p><p>Korra gets her bending restored by Aang as a past life/spirit. It seems equivalent to the past lives using the Avatar State while Aang isn't fully in control of it, yet. Aang's spirit goes into the Avatar State to bend Korra's energy. Korra doesn't need to at that moment.
