The suttas explain that dana offered to a perfectly enlightened Buddha brings greater fruit than a gift to an Arahant, which brings greater fruit than a gift to a Non-Returner and so on down the chain of enlightenment through to the unenlightened wanderers of other sects.
I'm wondering what the explanation for this kammic correlation is? What is it that makes it so?
