To be in silence is to let go of all external communication and to limit sensory impressions and to cease everyday responsibilities so that the mind does not have to deal with all new impressions and in that way has more space to listen to what is going on inside.
It is an opportunity to become present with what the mind has already received, release inner stress and discover underlying drives in the mind.
It gives the opportunity to find clarity of mind.
It can also lead to being able to see the difference between thoughts and the self.
Then arises a capacity to understand that the self is not dependent on what changes.
The thoughts come and go while the self remains and is constant, completely, all the time.
In that understanding there is a rest and a power that can be translated into actions even when the temporary is painful.
From that understanding, one can take support and live in more interaction with power and less in reaction.
