"In Tibetan Buddhism Hungry Ghosts (Sanskrit: pretas) have their own realm depicted on the Bhavacakra and are represented as teardrop or paisley-shaped with bloated stomachs and necks too thin to pass food such that attempting to eat is also incredibly painful. Some are described as having "mouths the size of a needle's eye and a stomach the size of a mountain". This is a metaphor for people futilely attempting to fulfill their illusory physical desires."
http://en.wikipedia.org/wiki/Hungry_ghostsThis idea of ghosts in many religions seems to be always present, and it seems a little over-present to me, in the light that we do not tend to see ghosts very often if at all.
The other day I read, in the Chinese meditation classic'The Secret of the Golden Flower', an interesting sentence which went: "If we do not meditate for a day, then we become a ghost for that day". This stuck with me for the next few days, as I have always had trouble keeping my daily practice consistent.
This idea that if we do not meditate, then we become a ghost, seems to infer that if we do not practice becoming closer to our natural physical bodies, we enter a world of floating bodiless ghosts - and namely 'hungry ghosts', because a lack of meditation will also allow our hungry desires to surface more.
This has illustrated this world of "hungry ghosts" a lot better for me, and it puts the mystical idea in a practical, observable context, which is always good from a Zen point of view.
It does seem that one often encounters such 'hungry ghosts' in society, who can encourage one to leave one's true body behind and drift with them looking for trash to 'eat'.
