Only Aakhirah is Eternal

From birth you go through so many changes. As a baby you are totally helpless. Then at 6 or 9 months changes begin to appear and you start moving around. Then the child becomes an infant and begins going to school and crèche. Then as one gets older and develops strength and power this same helpless baby starts claiming that who is greater than me. However, after some time the strength and power fades away. So this is the law of the universe that everything reaches its peak and then declines. The only thing that will continue is the Aakhirat.
