Avatar: The Last Airbender, Season 2

Aang:
I'm sorry, but I can't let go of Katara.

Guru Pathik:
Aang, to master the Avatar State, you must opens all the chakras. Surrender yourself.

Aang:
Okay, I'll try.

Guru Pathik:
Now think of your attachments, and let them go. Let the pure cosmic energy flow. (He meditates again, beginning to lets Katara go. We then see him suspended above the planet, facing a giant, glows version of himself in the Avatar State. He begins to walk towards it and his tattoos start to glow. Suddenly, however, he hears Katara scream and sees a vision of her in chains and begins to run towards her.)

Karata:
LET ME GO! [His tattoos fade along with the solid light beneath his feet, and so he falls back to the earth]

Aang:
AAAAAAGGGHHH!!! [shocked] Katara's in danger! I have to go! [Aang gets up and begins to runs off]

Guru Pathik:
No, Aang! Wait! Come back! [Aang slides down the roof before he stops at the edge] By choosin' attachment, you have no match to this locked the chakra. If you leave now, you won't be able to go into the Avatar State at all!

[After a moment's hesitation, Aang runs off]
