It's not that there isn't a method to it. It's that you're supposed to be removing yourself from judgment. Mindfulness is a non-judgmental head space. It's observing what is actually happening without thinking of it in terms of good or bad, so yeah, saying you're doing it "wrong" is kind of doing it wrong. lol That's why there is no "wrong" way to do it. You know? Another part of it is that meditation is showing up for yourself, so just sitting there doing it is doing it right.
Let me put this in terms of a mindfulness session:
You're sitting and all of a sudden a negative thought flies through your head. Having achieved mindful awareness, you would be able to observe this thought without judgment, so you wouldn't say "fuck, I'm doing this wrong because I had a negative thought." You would ideally either think nothing of it or think something like, "Oh, look. A thought." and move on with your practice. Meditation is NOT about clearing your mind. It's about sitting apart from the shit that floats through it. It's hard and you will "do it wrong" every time you sit. You make corrections, look for ways to observe non-judgmentally and move on. This is practice so when the shit hits the fan in real life, you are better at going "Oh, look. A thought."
Another example:
Say I'm walking along a trail and I come across muddy sludge. I can either choose to radically accept the muddy sludge by simply acknowledging its existence and finding a way around/away from the sludge without feeling bad or good about it or I can think, "Oh, great. There's fucking gross sludge in my path. Isn't that just like life? This sucks. Fuck this sludge. Fuck this walk. Fuck my day." Instead of labeling these things and increasing our suffering through negativity, we're better off just realizing the mud simple is. There is nothing good or bad about it. It's just mud that's there. Not liking it will change nothing except your mood.
