Silence in a person will initiate the inward journey towards understanding the self. The absolute silence for a longer time can increase the spiritual strength of the person. At the end, silence can make one feel their soul. Silence in a relationship can induce echo of thoughts and one may part with the other person. For a matured person silence will have no effect on the relationships.
Silence is a powerful tool which can be used for both constructive and destructive purposes. Loneliness can create silence in a person. Being lonely frequently is a good habit to reap the constructive results of silence. People who are achievers, have always felt the power of silence. Being silent to a person whom you feel missing, is destructive.
