life,what is life?

Everyone needs to know why did they came here for their life? What is the purpose of life for us? and what the purpose of our life? In this life, it's just a body, it's not we, who actual we are. it's a kind of a reaction that energy transformed into the faith. Every everything is new for every time. But how are we living? Can we really live with the true purpose of our life and the true beliefs of life? That's why we have to know the truth and learn how to find the truth. If you do not do it, then you just wasted your true energy. The real true energy, which is our real reality.
