In the “Buffering Lesson”, Brook talks about external and internal solutions. I don’t understand why anything external is a kind of buffering? For example, someone is feeling anxious and trying to use running, listening to music, meditation, or reading a good content to feel better. In my opinion, these are all external TOOLS that complement the internal work, not buffering. Even if they train the brain to look for an external solution for anxiety, they are not a substitute for the internal work, but the supplement. What will happen the next time that a more intense anxiety comes up? Can we use the same external tools? My answer is yes, why not? They’re still helpful. There is no harm in using them, if we accept that the main job is finding the internal solution.
