" Ask any number of people to describe a moment of “perfect” happiness. Some will talk about moments of deep peace experienced in a harmonious natural setting, of a forest dappled in sunshine, of a mountain summit looking out across a vast horizon, of the shores of a tranquil lake, of a night walk through snow under a starry sky, and so on. Others will refer to a long-awaited event: an exam they’ve aced, a sporting victory, meeting someone they’ve longed to meet, the birth of a child. Still others will speak of a moment of peaceful intimacy with their family or a loved one, or of having made someone else happy. The common factor to all of these experiences would seem to be the momentary disappearance of inner conflicts. The person feels in harmony with the world and with herself. Someone enjoying such an experience, such as walking through a serene wilderness, has no particular expectations beyond the simple act of walking. She simply is, here and now, free and open. For just a few moments, thoughts of the past are suppressed, the mind is not burdened with plans for the future, and the present moment is liberated from all mental constructs. This moment of respite, from which all sense of emotional urgency has vanished, is experienced as one of profound peace. "
