[Avatar TLA] Where did Guru Pathik come from?

He is apparently a non-bender with great spiritual insight. Which of the bending cultures is he from? He doesn't resemble any other characters in the show.

You don't gotta be a bender to be spiritual. This is going a bit meta, but the chakras thing was developed in a world without bending, so in a world where you actually interact with spirits and spirituality it's entirely possible there's entire groups of people who have developed this view of the world.

If he came from any bending culture he may be descended from the spirit benders that may or may not have existed alongside the other elements.
