Are there any Reformed theologians who support the practice of mindfulness (inner body awareness)?

As Eastern and Western religions begin to exchange lifestyles and practices, more and more Christians are participating in mindful meditation practices such as Zazen . When I refer to "mindfulness", I mean inner body awareness. This means you are both aware of your mental and physical state, therefor you are living and rooted in the present moment. Christian psych clinics are beginning to wonder if mindful meditation should be incorporated into their practices. My question is, can mindful meditation and living be consistent with biblical teachings? Are there any reformed theologians who support this view, and how do they defend it?
