The fact that the mind’s own choices can pierce its own ignorance underlies the Buddha’s most important assumption about the mind: It can be trained to awaken, to see the causes of ignorance and to bring them to an end. The primary step in this training is the first determination: not to neglect discernment. This phrase may sound strange — to what extent do we consciously neglect discernment? — but it points to an important truth. Discernment is insight into how the mind fabricates its experiences. This process of fabrication is going on all the time right before our eyes — even nearer than our eyes — and yet part of the mind chooses to ignore it. We tend to be more interested in the experiences that result from the fabrication: the physical, mental, and emotional states we want to savor and enjoy. It’s like watching a play. We enjoy entering into the make-believe world on the stage, and prefer to ignore the noises made by the back-stage crew that would call the reality of that world into question.
