Is inspiration divinely inspired? A brain blip? The byproduct or cause of mental disorder? A source of strength?

Does it come from within (the unconscious, the right brain) or without (God, a muse, your daimon)?  

I have my own ideas which I’m currently writing about and will be sharing with you soon. To kick off the discussion, here are two talks on this theme.

The first from Elizabeth Gilbert, most famously the author of Eat, Pray, LoveHere

The second from Amy Tan, most famously the author of The Joy Luck Club: Here.

What do you think? Where does your inspiration come from?
