Mindfulness is simply being aware of the present moment in a non- judgmental way. Being mindful gives us access to inner resources for coping effectively with stress, difficulty and illness.
Though mindfulness training has its roots in Buddhist meditation, the training is entirely secular. Research has shown that there are three emotional regulation systems in the brain and that many people are locked into two of these, namely fear of things we want to avoid (threat system) and striving for things we want to get (drive system). But there is a third system that is largely underdeveloped, namely the soothing system, which has the effect of bringing the other two systems into balance, resulting in more happiness and peace.
This system is strengthened though the practice of mindfulness that is rooted in kindness and compassion.
