The Discourse on the Lamp
80.
"What is the lamp in the world, what is the watchful one in the world;
What is the companion in work for those who live, what is its way of life?
"What nourishes the lazy and the diligent, as a mother her son;
What do beings live on, those living beings dependent on the earth?"
"Wisdom is the lamp in the world, mindfulness is the watchful one in the world;
Cattle are the companions in work for those who live, the plough is the way of life.
"Rain nourishes the lazy and the diligent, as a mother her son;
Beings live on rain, those living beings dependent on the earth."
