Most of the time, human beings act and behave as if they are going to live forever. They try to accumulate as much wealth as possible and hanker after power of different types- political, economic, physical… In their insatiable quest for wealth and power, they do not mind adopting foul means. They can easily do injustice to others if it serves their own interest or the interest of their near and dear ones. Human beings may be unjust to others not only for materialistic gain, but also out of jealousy, anger, etc.
When someone dies, especially some close one, people realize the futility of what they are doing. They suddenly become aware of the fact that whatever they have been running after will be left behind. All their possessions will fail to save them or their dear ones when it is time to depart. They realize that they cannot be sure of their own survival or the survival of those for whom they have been adopting foul means. They can see the meaninglessness of envy, anger, greed, etc.
When someone is lowered in the grave or his funeral pyre goes up in flames, the feeling of meaninglessness becomes all the more intense. Some people are so moved that they resolve to change themselves. They regret all the evil deeds they have been doing. For sometime, they may genuinely be very nice and kind to others.
Unfortunately, the change is very short-lived in most cases. Soon, people are caught up in the same grind and go back to hurting, harming and cheating others. They become as mean as ever. Someone’s death can make a person a better human being, but only for a brief period.
