interview by this author Gabor Mate about his book "In the Realm of Hungry Ghosts". It's about addiciton, behavior, childhood development, politics, a lot of stuff. He says the title comes from a Buddhist concept of different realms of being, one of which is the "Hungry Ghost Realm".
In the interview he says "people in it are depicted with large empty bellies, small mouths and scrawny thin necks, they can never get enough satisfaction, they can never fill their bellies, they're always hungry, always empty. Always seeking it from the outside" Kind of a haunting image i felt compelled to draw.
