The world of distraction spins around and around, while moving continuously to keep itself amused and entertained. It transports us to a world of fantasy, or a world of controversy, or competition, or of just about anything other than the one true existence that is right before us. Distraction keeps our heads turned in the direction of momentary pleasures, excitement, and delight.
On the other hand, the cool heart, with its spiritual energy, is the sobering factor that keeps us focused on worthier goals. It tempers the euphoria of petty fun. It settles us firmly down on Earth, grounding and sobering us with a clear view into life’s many facets in a balanced manner. The cool heart is unmoved by the intoxication of the world. The wise heart is the cool heart. It directs us to a profound state where we are liberated from the burden and stench of self-consciousness. Nothing can be better than that.
–Ajahn Sumano Bhikkhu, "Meeting the Monkey Halfway"
