Death is the simplest reality of our life. We are born, grow, live and, at last, die; this is a very simple reality. Death may be considered as something destroying life and opposite to life. For this reason, living becomes meaningful and valuable by denial of death. However, death is not merely an end, but it is a meaningful process. It is a process in which by the help of religion, life not only is not destroyed, but also is meaningful. Regardless of death, life would lose its originality. At the level of cognition, death “brings awareness of the situation” and in fact, it is a response to the question that what the nature of this world is. And at the level of performance, it demands a particular ethical procedure through which the functions of death would be organized. These functions are all the meaning that life receives by death. If there were not the thought of death, perhaps people would live differently.
