When the dragon roars, that roar is AUM.
When the dragon breathes fire, that fire is AUM.
Do you remember the episode of A:TLA when Aang and Zuko seek out the original firebending masters? The dragons roar AUM. You can see the bliss in Aang's and Zuko's faces.
AUM is roaring in my heart right now, like a dragon, and I'm in tears.
She. Is. Here.
