I'm not sure how such things work for you, but with Firebending, power comes from the breath. Breathe in, breathe out, and the fire moves with you.

[Iroh extends his hands, palms upward, and inhales slowly, then exhales.]

Let the warmth of the sun power you.

[Breathe in, breathe out. Embers pop to life in his open hand, then die out.]
