"You need to say 'I'm sorry' and 'Please forgive me' for being unconscious. it has nothing to do with regret, guilt, shame, or blame, but everything to do with realizing you've been asleep. When you bump into someone in the store, you say 'I'm sorry.' Why? Because you made a mistake. You were unconscious and did something while you were unaware. When you address the Divine and say those phrases, you are letting the Divine know you were unconscious. Forgiveness is one of the most powerful transformative tools you have. If you aren't willing to ask for forgiveness for being unconscious, you are probably blocking the Divine's flow in your life in other areas, too.
Having said all that, I once asked Dr. Hew Len what to tell people who complained about saying 'I am sorry.' He said, 'Tell them they don't have to say it.'"
