"As long as there is thirst in you, water can quench it; but you can live a kind of life in which you never feel thirsty; do not go in the sun, do no manual work, stay at home and relax and you will not feel the thirst. But then you will find no joy in drinking water. He who toils all day, enjoys the bliss of a good night's rest. This is ironical: if you want to enjoy the pleasure of a good night's sleep you have to work like a labourer all day. The trouble is that you want to spend your days like an emperor and your nights like a labourer."
