The prayer book that Teresa of Avila was using at her death contained her "bookmark", the outpouring of her own heart, translated:
Let nothing disturb you,
Let nothing distress you,
All things pass away:
God never changes.
Patience obtains all things.
He who has God
Finds he lacks nothing;
God alone suffices.
Lord, I long for such peace. I long to let go and rest in you. I long for such abiding in you, my true vine, and trusting you for the fruit of love.
