Meditative thinking: dwelling on what is near

In his 1955 speech collected in Discourse on Thinking, Heidegger distinguishes two ways of thinking: calculative thinking, which plans, counts and never stops, and meditative thinking, which takes the time to dwell on what is near and to question its meaning. He gives no protocol; this exercise, inspired by that text, suggests making room for such time regularly, without giving up our tools, saying "yes and no" to them at once.
