Look at the world from the highest point you can find. If you live in a mountainous area, climb to the top of a peak. If you live in a city, go to the tallest building and look down on life going on below you.
How does this perspective appear to you? Can you see people? Can you make out familiar shapes and sights that now appear unfamiliar? Can you imagine what a bird watches? Do you see both vastness and smallness at the same time?
See if you can get high enough to view, at the horizon, the actual curvature of the earth, the slight bending that is the reality of the planet on which we live. Astronauts have reported profound spiritual experiences when they first saw the earth from space. See if you can get high enough to have one as well. From the heights, you can put the reality of your every day life into perspective. Compare it to the grand sweep of nature, the enormity of the physical world.— Alan Epstein in How to Be Happier Day by Day
