There is this being called the hungry ghost. It's sort of a character in Tibetan Buddhism. This is supposedly an outcome of unfortunate rebirth.
I have been a hungry ghost. When I feel like punishing my husband with my sadness, when I can't engage my child because my face is flat, when I would rather be hungry than eat; I am a hungry ghost.
Last night, I scooped my baby up and we went to the bedroom and we played. We sang, danced, and bounced. We talked to our toys. She found mama's face had come back, and the ghost in me was chased off.
Every moment I am learning that it's never fixed for good. I will never clean my house and have it stay clean. The laundry will be done and undone. My marriage will not relocate to that place where it is permanently good. I will be reborn over and over again. Some mornings reborn with my Buddha nature shining through, then the next second reborn into a hungry ghost.
