“Now, Ānanda, gifts to the following persons may be expected to yield the
following returns.

To an animal, a hundred times.
To an unethical ordinary person, a thousand.
To an ethical ordinary person, a hundred thousand.
To an outsider free of desire for sensual pleasures, 10,000,000,000x 

But a gift to someone practicing to realize the fruit of stream-entry may be expected to yield incalculable, immeasurable returns.

How much more so a gift to a stream-enterer, someone practicing to realize the fruit of once-return, a once-returner, someone practicing to realize the fruit of non-return, a non-returner, someone practicing to realize the fruit of perfection, a perfected one, or an independent Buddha?

How much more so a Realized One, a perfected one, a fully awakened Buddha?”
