Silence and noise

Silence and noise are opposite to each other. But both are a part of life. I felt confused how can one be calm while you in midst of noise. I thought that only silence can bring me calmness. It never happened so. Thus I was in a search for something which can have silence and contain nose as well. Today I felt that if I am still inside and focused inside then I can contain both noise and silence. But this was a feeling not an analysis. Being still from inside doesn’t means being always slow and silent in your behavior.
