Both of them surviving this was bullshit lol
Haki functions as an Electromagnetic Barrier, which is why it allows people to take on some ridiculous force like this and redirect it.
Ya know.
I think it's finally time for me to make a thread detailing the Electromagnetism of Haki.
I LOATHE to say this next statement, and I mean this, I hate it: Rootbeer was correct, in that there is Diverging, and Converging Haki. I don't agree with his interpretations of it, but, there is "Outward" Haki, and "Inner" Haki, just as the Tao/Yin Yang operate on "In" and "Out".
Offensive use of physical Haki operates off of Yang, "Out". Defensive use of Haki operates off of Yin, "In."
Armament = Body.
Observation = Mind.
Conqueror's = Spirit.
At the very least Haki as a power system in entrenched in Buddhist philosophy, hence Zoro and Kaido's Buddhist themes.
The thread will heavily dive into Luffy, Zoro, and Kaido as representations of Buddhist/Eastern spiritual philosophy.
