Sitting on a stool in the middle of nowhere, we never hear a sound. The sound sometimes travels un-relentless, whether it is stagnant or moving. But you do not know that when sound becomes hearable, it could go within a split second.
It is like when a fly flies by and passes you; you may hear it as it passes.
Then, when you want to study, you must be in a quiet place, such as a library or your home, away from distractions.
It is not until you have learned how to stay silent that you learn the fundamentals of meditation, including how and when to break out of it.
