There’s not a good way to come into meditation or a bad way to come into meditation. It might feel preferable to show up feeling calm and spacious, but really meditation is about being awake and present to whatever is going on. You can’t critique your meditation in terms of good and bad. The only thing you can measure your meditation against is the question: “Was I present or not?” And even then, to say to yourself that you weren’t present is a result of the fact that you’ve been meditating and you recognized that fact. There’s some sense of awareness about what is actually happening.
