The book explores the nature of language and how it influences the way we perceive and interact with the world, showing how ordinary language, often loaded with judgments, evaluations and generalizations, can contribute to violence and conflict.

NVC, on the other hand, proposes an alternative language, centered on observing, feeling, needing and asking. The text demonstrates how we can transform our communication, replacing judgments with specific observations, expressing genuine feelings and connecting them to our needs, and formulating clear and positive requests. NVC invites us to recognize our responsibility for our own feelings and to practice empathy, seeking to understand the needs and feelings of others.

The book also addresses the importance of self-compassion, teaching how to deal with mistakes and regrets in a constructive way, replacing blame and self-criticism with a more compassionate and needs-centered perspective. The work, as a whole, aims to promote more peaceful and empathetic communication, seeking to build healthier relationships and contribute to the resolution of conflicts in a non-violent way.
