… Hindrances cannot arise when mindfulness is present. Mindfulness is attention to present-moment reality, and therefore, directly antithetical to the dazed state of mind that characterizes impediments. As meditators, it is only when we let our mindfulness slip that the deep mechanisms of our mind take over–grasping, clinging, and rejecting. The resistance emerges and obscures our awareness. We do not notice that the change is taking place–we are too busy with a thought of revenge, or greed, or whatever it may be. While an untrained person will continue in this state indefinitely, a trained meditator will soon realize what is happening. It is mindfulness that notices the change. It is mindfulness that remembers the training received and that focuses our attention so that the confusion fades away. And it is mindfulness that then attempts to maintain itself indefinitely so that the resistance cannot rise again. Thus, mindfulness is the specific antidote for hindrances. It is both the cure and the preventive measure.
