I am about to say Ha-mapil because I have to get up early on this strange day called "Labor Day" when most of society doesn't seem to have to labor at all because people are all off from work.
In Ha-mapil we say שתשכיבנו לשלום ותעמידנו לשלום You should us down to sleep in peace in raise us in peace. Shalom is from the word "shleimus" - spiritual perfection. We don't just strive for spiritual perfection during our active day but even when we lay down to go to sleep, throughout the night and when we wake up in the morning. Every moment should be suffused with spirituality.
