Quote and prayer by St Duchesne:
'Do not look back to the past, nor forward to the future, claim only the present, for it holds god's will'
'Lord, You alone are the Center in which I find rest. Give me Your arm to support me, Your shoulders to carry me, Your breast to to lean upon, Your Cross to uphold me, Your Body to nourish me. In You, Lord, I sleep and rest in peace.
