Already, mindfulness or meditation has been unbundled from its roots and rituals in eastern religions. The thought leaders refer to it as a "technology," not a form of spirituality.
My colleagues and clients are a lot busier with work than they had been. Less and less they are using terminology associated with spirituality. They don't mention signing up for a weekend retreat at a Buddhist temple. They aren't referring with great reference to world spiritual leaders such as Pema Chrodren and how much they learned from her latest video.
Maybe capitalism will always trump spirituality. When it was impossible to practice being a successful capitalist during The Great Recession, I practiced exotic forms of meditation three times a week in Zen center in New Haven, Connecticut. Non-stop I foisted the benefits on neighbors.
Then my business caught fire, again. That was the end of my spiritual journey. To help my professional performance I leverage the technology of mindfulness whenever needed. I swing by St. Philip's in the Hills Episcopal Church for its awesome lecture series (free). And, I predict the spirituality industry, much like the cupcake one, will be remembered as a sweet fad.
