“Is it possible, Lord, to see the visible results of generosity?”
And the Lord said: “Yes, it is possible to see the visible results of generosity.
The giver, the generous one, is liked and dear to many. This is a visible result of generosity.
The good and wise follow him. This is a visible result of generosity.
A good reputation concerning him spreads about. This also is a visible result of generosity.
Again, in whatever company he enters, be it nobles, Brahmins, householders or recluses, he enters with confidence and is untroubled. This is a visible result of giving.
And finally, the giver, the generous one, after death is reborn in heaven. This is a result to be seen hereafter. – Anguttara Nikaya III.38
