I was in the hospital with a blood clot and was told by the ER doctor that I could die at any moment.
Quotes like the above, ideas, feelings about meaning, thoughts about my wife and kids all were completely absent. I just felt blank and completely alone. No words or concepts or language could penetrate that feeling.
It's 'Epicurus' (auto correct strikes again?), and for all of his wisdom I think the detachment is not one that I subscribe to because fear of death can well come from the fear of no longer being there to support those that are dependent on you. If you limit your universe to yourself then it obviously gets a lot easier.
