@How to be wise
Hold a pen in your hand, look at it, feel it, tap it against the table, if you believe the present moment is all that exists then you’ll say yes, the pen is real because I directly experience it
now drop the pen, walk away, and look at a wall, search your direct experience for the pen, do you see it? Feel it? Can you remember the sound it made when it tapped? Contemplate on where the pen now exists, good ..
Now focus on the wall, walk up to it, feel it, knock it with your knuckles, look in your direct experience at what you believe is the wall
Now turn back around and pick up the pen again, ask yourself if it’s the same pen that you experienced before, does it have the same feel, does it look the same, sound the same?
Now ask yourself what is the difference from the pen you experienced before you focused on the wall to the pen you now experience?
