"It's an ability people from my country have. We can draw the heat from our bodies into fire and manipulate it using the chi flow as our bodies move," Iroh said, demonstrating by producing a small flame in his hand with a gesture. "It's said we learned from the dragons of our world, who are natural firebenders. Other nations in our world have different elements they can bend. The core principles are the same, but each element has its own philosophy and style taught to bend it. Or philosophies."

Iroh was quite good at learning from other elements and adapting them to firebending, but part of it was to understand how each element was both alike and different from the others. Neither fire nor lightning didn't flow the way water did, but they did flow.
