After Aang got shot with lightening from Azula, there’s this canon video from a video game or something Nickolodeon was doing that not a lot of people know about but basically, he reconnects with the past 4 avatars and his last one is Avatar Yangchen. After finding out that all Avatars have made human mistakes, and that no avatar was perfect, they have a really important discussion about why the avatar must be human instead of an all powerful spirit:
Aang: “Why is the Avatar Spirit human in every life? Wouldn’t fit be better if the Avatar was an all powerful spirit that never died?”
Yangchen: “I don’t think so. The Avatar must be compassionate towards all people and the only way to do that is to live with them. The Avatar must experience sadness, anger, joy and happiness. By feeling these emotions, it helps you understand how precious human life is so you will do anything to protect it. If you were an all powerful spirit living on the top of some mountain you wouldn’t have much in common with an ordinary person. So the avatar continues to take human rebirth and in each life, learns what it means to be human.”
Along his journey, Aang learns that by also being human, he is able to have one of the greatest strengths humans have, to love. The way that he is able to love and how others are able to love him make him human. He was able to be brought back to life because Katara loves him. Katara’s love and refusal to let him go ultimately saves Aang and bring him back to life. That’s what makes being the avatar so powerful. The fact that they don’t just have this incredible power, but because they are also able to love and be loved in return. By being human, he is able to have the strengths that humans posses.
That is why the Avatar state is only a DEFENSE MECHANISM as Avatar Roku mentioned. He isn’t supposed to be powerful all the time. He’s only supposed to use that in necessary times only. It’s also why he had to learn to control his emotions so he won’t trigger it out of anger.
Which is why the pointy rock thing, even though can count as DEM, it’s makes sense to the story in a sense that there’s a possibility that universe or the avatar’s spirits put that there for Aang so he was able to use his defense mechanism powers to help save the world. Just my thought/ theory. It may not be true but it works for me.
But can we also talk about how Avatar Yanchen also said “By feeling these emotions, it helps you understand how precious human life is so you will do anything to protect it.” Then Aang, despite feeling emotions of pain, grief and anger was still able to find balance balance between saving the world and spare Ozai’s life in the process. Aang, truly found balance between being a powerful spirit but also as a human and air nomad. Like this is why I freaking LOVE Aang as the avatar for his time period. He literally understand how precious human life is and used energy bending (which I think only the Avatar can do with their unique abilities) to save the world. Like he really used his Avatar powers to SPARE a life because he believed that ALL LIFE IS PRECIOUS. The monks taught him that and he was doing it for them too. Like he really combined his duty as the avatar and the teachings of his people who were wiped out and became Avatar Aang. He saved EVERYONE without having to do so at the expense of a single life. Which is why, Avatar Aang deserves all the freaking praise for being a freaking amazing Avatar, human and air nomad.
Not to mention, can we talk about the fact that he achieved this at TWELVE. Every Avatar before him trained to be the avatar at 16. Homeboy was only 12 and he was already out there bending all 4 elements in less than a year and became a prime example of what the avatar must to for the world. LIKE HOW CAN PEOPLE HATE HIM AND CRITIZE HIM SO MUCH. AANG IS BEST BOY <3
