One refuge, anchor, can be our breath. It is with us no matter where we are, no matter what our emotional state is. The Spirit of God is in our breath. It is a gift. Our breath is a sign that God is with us. Thich Nhat Hanh suggests watching the breath from a point 2 fingerwidths below the navel, and even putting our hands at that point to make it easier to focus. Just watch the breath without trying to control it. Feel your hands moving outwards as you breathe in and back in again with each out breath. After some time, you will feel calmer as your breath naturally slows down. You will be more calm than when you were overcome with upsetting feelings and emotions.
Thich Nhat Hanh also suggests you can invite the Jesus in you to breathe for you. Then you can watch Jesus breathing in you, you can bring awareness to God’s presence in you. After witnessing the breath for some time, it will automatically slow down, and the mind will be calmer.
