The unintentional act of being distracted while attempting to meditate due to the realization that you are, are not, or should be meditating. Also refers to excessive self-awareness and self-consciousness pertaining either to one's mind or body, occurring during or interfering with successful meditation practices. Common in persons meditating for the first or second time, or who don't believe in or agree with the premise of meditation. Sometimes accompanied by or triggered by embarrassment about the fact that they are meditating.
Ex 1: Whenever I finally started to relax and lose myself in the meditation exercises, I would think, "Ok, it's working now!" This metatation always caused me to lose my hard-won focus.
Ex 2: A couple times I almost started to fall into the rhythm of the Yoga class, at which point I would ask myself, "What am I even doing at a stupid Yoga class?", the metatation jolting me back into my crowded, disorganized thinking pattern and daily worries.
