I don't have difficulty with this. Doing nothing, thinking about nothing, and simultaneously feeling perfectly at ease just comes naturally. I know that my experience is not universal and that many people do struggle with this. If you struggle with this and you were wondering, serenity really is very nice, and I wish I could share it, and I'm sorry that I can't.
