Aim for harmony with the universe.
I consider peace is an illusion. To explain this let me introduce you to Mars. There are dedications and temples to Mars throughout the Roman and Celtic world, acknowledging how important Mars was to ancient people. Many will know Mars is the god of war, few will know that Mars is a patron of healing and agriculture. Through Mars plants grow, acknowledging the saying of Heraclitus “strife is justice,” through strife is a becoming. Through conflict Mars brings about healing and growth.
Lets look at science. This universe is a huge self-ordering energy system, consisting of variables such as galaxies, planets, you and me. Within this energy system is an eternal struggle between order and chaos. The force behind chaos is entropy, which adds or subtracts energy to and from the variables that make up the universe, sending the system into disorder. Naturally the universe creates counter forces to restore order, thus it may add energy to a disordered variable leading to complexity, in the same manner as the USA developed from States joining the Union, or by releasing energy leading to simplicity just as the USSR broke down into many smaller nation states. The nature of the universe is towards harmony rather than peace, a constantly rolling cycle of balancing out the disorder created by entropy.
Thanks to entropy, the most powerful force in the universe, which both science and mythology agree will slay this universe, there will always be strife in our lives and this world. Whilst they exist lions will always kill, earthquakes will rumble, storms roar and floods drown. Humanity has chosen through their hubris, ignorance and control to fight against the natural laws and processes of nature, ironically causing more entropy for themselves, rather than following the path suggested by Mars of balancing out entropy leading to healing and growth.
