“The conceptual lens through which we view (a situation) largely determines how we feel about it. This is one of the ways our thinking about an experience changes the character of the experience. The frame we put around the present moment is important (…) But it seems possible to experience life more nakedly than this, to experience it without an obvious frame.”
Sam Harris, speaking at the 2012 Global Atheist Convention in Melbourne. After making this point, he leads the audience through an exercise in mindfulness (beginning at 29:30.) The stated subject of his talk is death. Really, it’s life.
