Meaning of "Perpetual Black Second" by Meshuggah

"Perpetual Black Second" delves into the theme of being haunted by one's own actions and the perpetual cycle of regret and self-loathing that can result from a moment of anger and violence. The lyrics explore the idea of being consumed by a single moment of hatred, unable to escape the relentless replaying of that moment in the mind. The constant punishment of reliving that one second is likened to being held within a visualization, with the regretful soul animated by its own demons. The lyrics depict a struggle with inner darkness, acknowledging the presence of a ferocious demon within, and the desperate plea for forgiveness for the evil actions committed in that black second. The song highlights the destructive power of one's own anger and the inner turmoil that can result from succumbing to violent impulses.
