Purpose matters.
QuotesAlong roads I have had banyan trees planted so that they can give shade to animals and men, and I have had mango groves planted. At intervals of eight krosas, I have had wells dug, rest-houses built, and in various places, I have had watering-places made for the use of animals and men. But these are but minor achievements. Such things to make the people happy have been done by former kings. I have done these things for this purpose, that the people might practice the Dhamma.
