Oh god this brings out the meditation snob in me.  Very relevant article, part of the growing body of research that shows that meditation techniques based on concentration or control are hard work & people don’t keep them up  Apart from daft pic, most people do their TM on the tube or bus home, sitting comfortably – that’s why many call it “real meditation,” cause it’s so darn easy!

* Letting your mind wander is more effective than concentrating on emptying your head of thoughts, scientists said
* Researchers from St Olavs Hospital in Trondheim and the University of Oslo used MRI scanners to look at brain activity during meditations
* Concentrating on ‘nothing’ is only as effective as resting
* Meditation is practiced by millions of people but little is known about how it works
