Here are some key quotes:
"The fashion is not confined to Silicon Valley: the mindfulness movement can be found in every corner of the corporate world. Rupert Murdoch has a well-developed bullshit detector. But earlier this year he tweeted about his interest in transcendental meditation (which he said “everyone recommends”). Ray Dalio of Bridgewater Associates and Bill Gross of PIMCO are two of the biggest names in the money-management business, and both are regular meditators. Mr Dalio says it has had more impact on his success than anything else.
Does all this mindfulness do any good? There is a body of evidence that suggests that some of its techniques can provide significant psychological and physiological benefits. The Duke University School of Medicine has produced research that shows that, in America, an hour of yoga a week reduces stress levels in employees by a third and cuts health-care costs by an average of $2,000 a year. Cynics might point to the evidence that a walk in the countryside has similar benefits. They might also worry that Aetna, an insurer which wants to sell yoga and other mindfulness techniques as part of its health plans, is sponsoring some of the research that supports them. But it seems not unreasonable to suppose that, in a world of constant stress and distraction, simply sitting still and relaxing for a while might do you some good."
