You need to figure out how to empty the Monkey Mind. Look into Fussion Gym at 12th and Sansom. They have, or did at one time, a free Sunday meditation session. It was one of the nicest most mind-freeing hours I had, though it was very hard to not think, and not be the worrier!
I never heard it put "empty the Monkey Mind", but that is what I need. I went to one free guided meditation at Ease Studios at 15th & Walnut last month. I agree, it was much easier to concentrate in a space away from clutter and distractions and most importantly, having a soothing voice talk you into meditation.
