Just as our body needs good, nutritious food every day, our mind also needs the nutrition of good thoughts every day. If we eat nothing but junk food, our body will become unhealthy and sick. Similarly, bad thoughts will make our mind sick and weak. Instead, we must uplift the mind by feeding it pure thoughts. Only then will we obtain peace in life.
In the span of this brief human life, the amount we can learn about the external world will always be extremely limited. We cannot call this information true knowledge. Only through meditation can we grasp the depth, pervasiveness and fullness of life. We would never allow strangers to park their vehicles in our driveway. But do we exercise this same vigilance when it comes to the thoughts that park themselves in our mind?
Using our discernment, we should be able to identify the thoughts worthy of a place in our mind, and discard the unworthy ones. The goal of meditation is to make the agitated mind peaceful and still. When thoughts cease through meditation, the mind becomes more pure and subtle. The mind becomes more tuned to the rhythm of the universe. In that stillness, the unknowable knowledge becomes knowable.”
