Breath prayer is perhaps the simplest of practices. It consists of pairing a short Scripture, or phrase, with your inhale and your exhale. It is particularly helpful in situations of stress or tedium, when you desire to become aware that God is with you. Here are some ideas, but this is a very personal practice. Choose one that fits and repeat it with the rhythm of your breath as many times as you wish. You may adapt your favorite short passage or your name for God to this as well.
Inhale: Jesus. Exhale: Have mercy on me.
Inhale: God, I am here. Exhale: You are here.
Inhale: Abba. Exhale: I belong to you.
Inhale: Holy Spirit. Exhale: Help.
Inhale: You are my shepherd. Exhale: I have all that I need.
Inhale: I come to You. Exhale: You give me rest.
