29. Samasūpakapaṭiggahaṇasikkhāpada 29. The training rule on receiving the right proportion of bean curry
Tena samayena buddho bhagavā sāvatthiyaṁ viharati jetavane anāthapiṇḍikassa ārāme. At one time the Buddha was staying at Sāvatthī in the Jeta Grove, Anāthapiṇḍika’s Monastery.
Tena kho pana samayena chabbaggiyā bhikkhū piṇḍapātaṁ paṭiggaṇhantā sūpaññeva bahuṁ paṭiggaṇhanti …pe…. At that time the monks from the group of six were receiving almsfood with large amounts of bean curry. …
“Samasūpakaṁ piṇḍapātaṁ paṭiggahessāmīti sikkhā karaṇīyā”ti. “‘I will receive almsfood with the right proportion of bean curry,’ this is how you should train.”
Sūpo nāma Bean curry:
dve sūpā— muggasūpo, māsasūpo hatthahāriyo. there are two kinds of bean curry, to be taken with the hand: mung-bean curry and black-gram curry.
Samasūpako piṇḍapāto paṭiggahetabbo. Almsfood should be received with the right proportion of bean curry.
Yo anādariyaṁ paṭicca sūpaññeva bahuṁ paṭiggaṇhāti, āpatti dukkaṭassa. If a monk, out of disrespect, receives much bean curry, he commits an offense of wrong conduct.
Anāpatti—There is no offense:
asañcicca, if it is unintentional;
assatiyā, if he is not mindful;
ajānantassa, if he does not know;
gilānassa, if he is sick;
rasarase, if it is any food apart from bean curry;
ñātakānaṁ, if it is from relatives;
pavāritānaṁ, if it is from those who have given an invitation;
aññassatthāya, if it is for the benefit of someone else;
attano dhanena, if it is by means of his own property;
āpadāsu, if there is an emergency;
ummattakassa, if he is insane;
ādikammikassāti. if he is the first offender.
Navamasikkhāpadaṁ niṭṭhitaṁ. The ninth training rule is finished.
