"The greatest reality of life is death".
Today we are wandering in the world in search of education , in starting of a business , in finding a job opportunity at the age of 25-35. But stop for a while and pay attention on your life , focus on the place you stand . Are you present in your childhood in which you just live on the mercy of your parents , in your busy days of life when you are struggling for your livelihood for a better future , or enjoying the free life time after retirement ? Making fun in your single life or enjoying a married life in short which part of life and which position of life you stand just focus all these parts are leading to the death.
We just live a very short life . How a human can imagine this short life in which we come to the planet Earth for a short time and doing what we want and than met our end . It seems like some kind of joke if there is no concept of the judgment day .
Just forget the judgment day for a moment and think what is the purpose of this life ? Where are the mischiefs of childhood and where is the time when we were spending a married life was it just for "spending" in any way you want ? Exactly "No" it's not as it seems .We human cannot imagine a society without the day of judgment .
"The life on Earth is very short so prepare yourself for the life after death".(Kamal)
So the death is not the end of a human there is a complete concept of the life after death not only in every religion but also it is the simple thought of every human who have a useful mind.
