Reading this excerpt from Thich Nhat Hahn's The Miracle of Mindfulness, I found myself calmed by it. So I thought I would post a link to it for you. The words below came forward to me.
For those who are just beginning to practice, it is best to maintain a spirit of silence throughout the day. That doesn't mean that on the day of mindfulness, you shouldn't speak at all. You can talk, you can even go ahead and sing, but if you talk or sing, do it in complete mindfulness of what you are saying or singing, and keep talking and singing to a minimum. Naturally, it is possible to sing and practice mindfulness at the same time, just as long as one is conscious of the fact that one is singing and aware of what one is singing.On my first retreats I realized forcefully that keeping silence was a great relief to me. That was connected to my sense of responsibility to others rather than myself, and to my anxiety. Those insights were important, but the teaching was in the sense of laying down a heavy burden.
You can call it awareness or "a day of mindfulness" or "keeping the Sabbath holy." What it is, is a gift to yourself.
