Sisyphus kidnapped the God of Death for a time, so that there would be no death in the world. Finally, because he offended the gods, in order to punish Sisyphus, the gods asked him to push a huge boulder to the top of the mountain. Because the boulder was too heavy, it would roll down the mountain again before reaching the top of the mountain, and all previous efforts were wasted. So he kept repeating this thing endlessly, and his life was slowly consumed in the labor.
Intention: Hard work and persistence lead to happiness.
