Why do we get happiness from external things?

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. For someone who has achieved a goal, completed a task, or won a victory, the tension they have long carried with them relaxes. The ensuing sense of release is felt as a deep calm, free of all expectation and fear.
But this experience is just a passing glimpse brought on by a particular set of circumstances. We call it a magic moment, a state of grace. And yet the difference between these flashes of happiness seized on the fly and the immutable peacefulness of the sage, for instance, is as great as that between the tiny section of sky seen through the eye of a needle and the limitless expanses of outer space. The two conditions differ in dimension, duration, and depth.
Even so, we can learn something from these fleeting moments, these lulls in our ceaseless struggles; they can give us a sense of what true plenitude might be and help us to recognize the conditions that favor it.
