The poem promotes unity and understanding between all people. It argues that beneath superficial differences like uniforms or nationality, all humans are fundamentally the same. We all experience the basic elements of life like sun, air and the changing of seasons. Our hands and labor are also similar. The poem aims to prevent hatred and conflict between people by reminding us of our shared humanity. It suggests we betray ourselves if we take up arms against others, as we all inhabit the same human earth.
