It analyzes how people use their beliefs and religion as help in restoring balance necessary for attaining mental health. The paper also points out the significance of spirituality and spiritual peace as the component of mental health and its preservation. The purpose of this paper is to show that religious people deal easier and better with dangers which can damage mental health. That is noticed through longer lifespan and rare illnesses.
