Sometimes I hear lawyers respond to the thought of meditating with a concern that doing so will put out the fire in the belly. I tell them mindfulness will focus the fire, not smother it. Here's some research that will help make my point.
In "Mind Fitness and Mental Armor: Training the Mind to Improve Operational Effectiveness and Build Warrior Resilience" [PDF] [Note: article no longer available - read more here] (to be published in Joint Force Quarterly) you can read about military personnel engaging in mindfulness training. This article by Elizabeth Stanley and Amishi Jha is excellent and I highly recommend it to you.
From the Conclusions:
In addition to its beneficial effect on stress, mind fitness training can help to optimize warrior performance by cultivating ... competencies in mental agility, emotion regulation, attention and situational awareness. In other words, mind fitness training could provide greater cognitive and psychological resources for soldiers to act ethically and effectively in today’s morally ambiguous and emotionally-challenging operational environment.
Anyone still not using some mindfulness practice?
