If you cannot be still with your own thoughts in life, there is an issue. The issue here is that you have not yet used silence to your advantage. Silence is a weapon, anyone who has ever been a victim of a silent treatment knows this. That being said, you have to master it, so that this weapon first and foremost cannot be used against you; but secondarily you should be able to use it to defend yourself. Silence kills stupidity. You can't argue with stupid, as the old saying goes; so silence goes a long way.
The mind needs silence to recharge from the insanity of the world. They have actually proven that the sounds of nature start to relax/reprogram you. But even nature is semi-quiet at night (unless you live in a place with a lot of the cicadas). Animals need silence, why wouldn't we? Meditation is a good door to fill this silent need, but frankly, there are many ways to skin this proverbial cat. The main point is that if you cannot be silent with yourself; if someone uses the silent treatment on you, you will crack like an egg. One of the greatest joys in life is letting crazy people know that you are beyond their attacks. This can happen in the corporate world, your personal life etc etc.
Whoever wants to silence you, will first use silence themselves to disregard your perspective and make themselves unavailable to any meaningful dialogue. Its one of the main tools of the passive-aggressive. But if you master silence first, then they will be at the disadvantage! Silence can kill a weak person, so use it with discernment. Don't hurt someone if you don't absolutely have to.. Just get out of their scope of reach. But if it comes down to it, silence scares pretty much anyone you use it against.
Great post, It is really meaningful.
