Lorica

A lorica is a prayer of protection.  St. Patrick had a lorica.  You could write your own, but here is one of my favorite written prayers by St. Francis of Assissi:

Lord, make me an instrument of thy peace.
Where there is hatred, let me sow love.
Where there is injury, pardon.
Where there is doubt, faith.
Where there is despair, hope.
Where there is darkness, light.
Where there is sadness, joy.
O divine Master, grant that I may not so much seek
To be consoled, as to console;
To be understood, as to understand;
To be loved, as to loved.
For it is in giving that we receive,
It is in pardoning that we are pardoned,
It is in dying that we are born
To eternal life.

Happy St. Patrick's Day (ya know, last Saturday); and better yet, Happy Easter!
