David Gelles is a business reporter for the New York Times and its business blog, DealBook, where he writes about mergers and acquisitions, capital markets and corporate governance. He is also a longtime meditator and spent six months in India studying with Zen masters, Tibetan rinpoches and Burmese monks. His book Mindful Work is about how mindfulness is boosting leadership, reducing stress and improving health in the workplace, from Apple to Goldman Sachs. It tells of a quiet revolution reshaping some corporates as some of the world's most dynamic entrepreneurs and businesspeople are starting to change how a successful business is run. A new breed of mindful managers are using meditation, yoga and other Zen techniques to focus on feeling good while making money - and using the money to do good too.
