This was said by the Blessed One, said by the Arahant, as I have heard:
“Bhikkhus, there are these three bases for meritorious action. What are the three? The base for meritorious action |through generosity::produced by giving, charity [dānamaya]|, the base for meritorious action |through virtuous conduct::defined by ethical behavior [sīlamaya]|, and the base for meritorious action |through meditation::developed by meditation [bhāvanāmaya]|. These, bhikkhus, are the three bases for meritorious action.”
The Blessed One spoke on this matter. In this regard, it is said:
“One should train only in merit,
which brings long-lasting happiness;
Cultivate generosity, virtuous conduct,
and develop |a mind of loving-kindness::a mind of benevolence, a friendly heart [mettacitta]|.
Having developed these qualities,
the three causes of happiness;
The wise one re-arises,
in a non-afflictive and pleasant world.”
This matter too was spoken by the Blessed One, as I have heard.
