Sit Down and Shut Up
The great secret of how to “Sit Down and Shut Up” involves practice. Anything you do every day, you WILL get good at. When thoughts, internal dialogue, feelings, and strange odors inevitably arise, look to their source and impermanence, then get back to non-think. Sometimes I think of my brain as a muscle, and relax it into non-think just as I would get a muscle to relax. It also helps to close your eyes and look into nothing, and be in that nothing like you are nothing, like you stepped into it. Also earplugs, not sure why they help, but they do. Lastly, remember that if you try to sit down and shut up for an hour, and only 5 cumulative minutes were done right, that 5 minutes is fantastically awesome and will effect you positively forever.
