Silence is a self-rewarding activity. Not only does it calm the mind, but it also creates a framework for concentration and contemplation. It is a recreative activity that heals the very inmost of a person.
Solitude and silence can be gratifying things if you learn how to use them. Those practising meditation know how hard it is to stop the constant chatter of the mind. There is nothing wrong with having thoughts, but having too many ideas can be exhausting and contaminating for vision.
