The quote "When you begin a journey of revenge, start by digging two graves: One for your enemy and one for yourself" implies that seeking revenge can have harmful consequences not only for the target of your revenge but also for yourself. It suggests that engaging in a cycle of vengeance can lead to destruction for both parties involved. The metaphorical meaning behind this quote is that revenge often leads to a loss of one's own well-being and moral integrity, in addition to causing harm to the person seeking retribution. It emphasizes the idea that holding onto anger and seeking revenge can be self-destructive. While the quote does not explicitly say that one should never take revenge, it does caution against the potential consequences of revenge and highlights the importance of considering the impact of one's actions on both oneself and others. It encourages reflection on the outcomes of seeking revenge and the potential escalation of conflicts that can arise from it.
