The practice of mindfulness has its origins in Buddhist tradition. It is about paying attention to the here and now in new and more nurturing ways. It is also about allowing yourself to be as you already are. This is not only healthy but also has the potential to be healing.
It is not about trying to get anywhere. It is simply a matter of being aware of where and how you are and allowing yourself to be that. With increased awareness you can respond to situations with choice rather than react automatically.
It makes life more enjoyable, interesting, vivid and fulfilling. It also means facing up to whatever is present, even when it is unpleasant or difficult. In the long run this reduces stress and unhappiness.
A word of caution, mindfulness is not a panacea; a cure for all ills, nor is it about seeking happiness or emptying one's mind. It is just simply cultivating awareness.
