In Buddhist and other texts throughout the Far East, Hungry Ghosts are depicted as teardrop shaped, with bloated stomachs and necks too thin to pass food—representing our futile attempts to feed ego patterns: we can never find satisfaction, like drinking salt water to quench our thirst.
This is a useful analogy for our addictive personality patterns. And it won't help anyone to suggest, metaphorically, "You needn't be so hungry" . . . or worse . . . "You really should go on a diet."
Instead of theorizing about or labeling behavior, it's important to become aware of our Hungry Ghosts and observe them with compassion, not judgment--to identify, embrace, and learn about the nature of our hungers.
