One thing you should also remember, the cards have no memory. Just because you are wining a lot of hands early and hitting the board well things will balance out sooner than later. If you start to play more hands that you usually would you will eventually lose to bigger hands or just plain start missing. Look at the tournaments you play and how many times do you see a chip leader early on with the monster stack 2 to3 times the 2nd biggest stack? Check just before the money bubble and you will see they are long gone by that point. There luck runs out. Next time you get on a roll and feel like opening it up some more try to tighten us just for a while. You will love the results.
As for meditation, I actually meditate before and after every tournament I play now and listed to meditation music as I play. I started this a little over a year ago and it has worked wonders for my. I am playing smarter thinking poker and my attitude and results have improved. I highly recommend it.
