How long can you go without speaking?
How long can you go without THINKING?
Can you look at an object and not say in your mind what it is?
Practice the Meditation technique below for two weeks. After the two weeks are up ask yourself the same questions.
How long can you now go without thinking?
Can you look at an object and not identify it?
My guess is that you will be able to go much longer without thinking and are starting to realize the uselessness and waste of time of mentally identifying everything you touch see and hear.
