The Legend of Korra, Book Two: Spirits

Bumi:
Jinora's spirit, do you hear me? It's your Uncle Bumi.

Tenzin:
Ah, this isn't working. We can't just randomly wander the spirit world, call out for Jinora, and expect to find her!

Bumi:
We just need to employ the simple rules of tracking. First we locate her footprints... then we follow them.

Kya:
Do you even know what spirit footprints look like? Do spirits even leave footprints? Face it, your tracking skills won't work in the spirit world. Let me try something. [sits down and meditates] Ommmm... Jinora is over there. I feel a lot of spiritual energy coming from that direction.

Bumi:
We're in the spirit world. There's spiritual energy in every direction!
