What is the most wonderful thing in this world?

Similarly, Maharaja Yudhisthira was asked by Yamaraja, “What is the most wonderful thing in this world? Can you explain?” So Maharaja Yudhisthira answered, “Yes. The most wonderful thing is that at every moment one can see that his friends, his fathers, and his relatives have died, but he is thinking, ‘I shall live forever.’” He never thinks that he will die, just as an animal never thinks that at the next moment he may be slaughtered. He is satisfied with the grass, that’s all. He is satisfied with the sense gratification. He does not know that he is also going to die.
