“Bhikkhus, there are these five timely gifts. What five?
(1) One gives a gift to a visitor.
(2) One gives a gift to one setting out on a journey.
(3) One gives a gift to a patient.
(4) One gives a gift during a famine.
(5) One first presents the newly harvested crops and fruits to the virtuous ones. These are the five timely gifts.”
At the proper time, those wise,
charitable, and generous folk
give a timely gift to the noble ones,
who are stable and upright;
given with a clear mind,
one’s offering is vast.
Those who rejoice in such deeds
or who provide other service
do not miss out on the offering;
they too partake of the merit.
Therefore, with a non-regressing mind,
one should give a gift where it yields great fruit.
Merits are the support of living beings
when they arise in the other world.
