Yes, you can spread kindness without saying a single word. A meditation practice known as metta is all about cultivating compassion for yourself and others via kindness mantras.
You can tailor the mantra to suit yourself, provided the focus is sending kind thoughts to yourself, then those you love, then those you feel impartial toward and finally those you dislike. Studies show that the benefits of having a loving-kindness meditation practice on social and emotional well-being are far-reaching, so it’s a good thing to start with your kids from a young age.
One study even showed that a single seven-minute loving-kindness meditation made people feel more accepting of themselves and more connected to and positive about others — both loved ones and total strangers.
