We are, perpetually, dying and being reborn -- our bodies are burial grounds.
Or, if you prefer, haunted houses. Sometimes, these spirits/old selves return unbidden, depending on the hold that they still have on us.

Liberation might seem like a hairline away from depression, in the sense of having outlived ourselves. But instead of mourning, or longing for who we once were, we feel unburdened to become nobody or everybody. _/|\_
