Pray St. John of the Cross’ “Prayer of Peace” to calm your mind

O Blessed Jesus, grant me stillness of soul in Thee. Let Thy mighty calmness reign in me. Rule me, O thou King of gentleness, King of peace. Give me control, control over my words, thoughts and actions. From all irritability, want of meekness, want of gentleness, O dear Lord, deliver me. By thine own deep patience give me patience, stillness of soul in Thee. Make me in this, and in all, more and more like Thee. Amen.
