NVC teaches the skill of honesty. It teaches people to engage with one another with an  intention to establish a quality of connection that leads to everyone's needs being met peacefully by bringing attention into the present moment .

It teaches people how to listen to others in such a way
that helps us see past an other's anger, criticism, and hopelessness etc to see what need of theirs are not being met, and listening for ways to help them fulfill their needs and desires, or to make request of others in a way that fulfills the request or needs.

Through its emphasis on deep listening-to ourselves as well as others -NVC fosters respect, attentiveness and empathy, and engenders a mutual desire to give from the heart.
