Silence allows you to watch your mind and become aware of the thoughts that you may be acting on unconsciously. When you see the thoughts, you can make a conscious choice to act on the thought or change your mind, instead of going along with the noise. I have seen people who don't want to look at themselves keep going until something happens that makes them stop — a sickness or an accident — but it gives them that reflective, quiet space where they can face what is difficult in their mind. We each have a unique purpose to fulfill in this life and inklings can come in those quiet moments.
