SN1.47: Vanaropasutta

“For whom does merit always increase,
Both by day and by night?
Who are the people going to heaven,
Established in Dhamma, endowed with virtue?”

“Those who set up a park or a grove,
The people who construct a bridge,
A place to drink and a well,
Those who give a residence:

“For them merit always increases,
Both by day and by night;
Those are the people going to heaven,
Established in Dhamma, endowed with virtue.”
