For most people, the first time they see the Grand Canyon or Yosemite Valley or Niagara Falls, their eyes widen, their jaws hit the floor and life is quiet for a moment. In other words, they are in awe.

Researchers often describe awe as an emotion that combines an experience of vastness with both pleasure and a fear of the unknown. While many of us might consider these moments rare, ephemeral and tricky to reproduce, a few scientists are finding that this reverence is a skill that can be cultivated and has remarkable mental health benefits.
