Such a beautiful prayer. Praying it is like falling through the clouds after a tough climb to the top on a path covered by rocks which clawed and scraped you as you went through, and knowing that the Lord has you in His arms, wrapped up and safe...enjoy the ride! :)
O my God, I am heartily sorry for having offended Thee, and I detest all my sins, because I dread the loss of heaven, and the pains of hell; but most of all because they offend Thee, my God, Who are all good and deserving of all my love. I firmly resolve, with the help of Thy grace, to confess my sins, to do penance, and to amend my life. Amen.
