In THE SNOW LEOPARD, Peter Matthiesen describes his son, Alex:

In his first summers, forsaking all his toys, my son would stand rapt for near an hour in his sandbox in the orchard, as doves and redwings came and went on the warm wind, the leaves dancing, the clouds flying, birdsong and sweet smell of privet and rose. The child was not observing; he was at rest in the very center of the universe, a part of things, unaware of endings and beginnings, still in unison with the primordial nature of creation, letting all light and phenomena pour through.
