Of course, in life we do have things we must get done to meet some deadline, but most things can be left undone for a while. If you are OK with that, you have abandoned yourself to God to some extent. We all are going to die and I am sure on that last day, there will be many things still unfinished or not wrapped up yet, and we'll just have to let go. Since we do not know the day we die, why not let things go starting right this moment? We are just passing through on earth, so don't let anything tie you down. Remain free and enjoy life.
