Pablo Neruda was a Chilean poet who won the Nobel Prize for Literature in 1971. This poem expresses Neruda's desire for silence, stillness, and inactivity as a respite from the frantic pace of modern life and destructive wars. He urges people from all countries and backgrounds to set aside their differences and unite in profound silence, which would allow for introspection and understanding of oneself and alleviate sadness. The poem contrasts silence with war, destruction, and lack of understanding of oneself or others. It suggests that periods of stillness and silence can be profoundly insightful and teach humanity to value life over death.
