This couplet literally means 'Sleeping folk, wake up! Wake up, oh brother, wake up!' It is a direct call to awaken those who are slumbering.

This couplet is a powerful and direct call to awaken. It urges those who are 'sleeping' – perhaps metaphorically, meaning unaware, inactive, or complacent – to wake up. The repetition and the address 'oh brother' make it a warm, personal, and urgent appeal. It's a reminder to be present, to be aware of one's surroundings, or to take action when needed. It asks us to shake off our slumber and engage with life fully, encouraging vigilance and active participation.
