Jealousy. Is there any other emotion quite as toxic?
There's a kind of strength in anger; a dignity in despair. Sadness always bubbles just under the surface of compassion, often as the flipside to love or joy. But jealousy resides inside the lowest, meanest, dirtiest part of ourselves. As an emotion, it's where we humans become truly hateful.
Because we're only jealous of others when we hate something about ourselves. It's so much easier to turn an envious eye towards others' happiness, success, beauty, etc. than to cast that eye upon ourselves. And who can deny that sometimes it can be fun to revel in jealousy, to let yourself go that dirty place and slide around in the muck? Come on, admit it... we all just need to feel mean sometimes. And jealousy makes it safe; the only person we're being mean to is ourselves.
