'Your life span is prolonged
when you are full of joy,
when you are calm and filled with pure thoughts.
When you are filled with envy,
anger, hatred and conceit,
your life span gets shortened.
Sleeplessness ruins the health
even more than lack of food.
Envy torments a man all the time.
These troubles lead to shortening one's life...
Envy drives man crazy by depriving him of his sleep.
In that condition, he cannot relish his food.'
