We can express the generous giving of loving kindness with our body, our speech, and our mind. In the big, crowded cities in the world, an example of extending generosity by using our bodies is simply by smiling at another person; having received our smile, they will find themselves feeling happy for the rest of the day. Speaking sincerely from our hearts and not just making superficial small talk is a way to be generous with our speech, and it is possible that in this way we can give really significant and lasting benefit to others. In addition to making them feel happy for the rest of their day, in subsequent days when they reflect on the words we have spoken to them, it is possible that they will gain continued benefit. It may even be that words we speak to another person will prevent them from doing something like taking their own life, and so generosity of speech can even be a way that we rescue other people.
