A blemish related with bhikṣā (accepting food etc. by going to houses for collecting them in conformity with the canonical instruction);
if the giver washes hands, ladle etc. with Sacitta water (i.e., water which is possessed of water-bodied beings) on seeing the monk approaching his house, for giving bhikṣā to the monk, and if the monk accepts such food, then there is the blemish called Puraḥkarma.
purekammaṃ nāma jaṃ sādhūṇaṃ datthūṇaṃ haṭṭham bhāyaṇaṃ dhovai taṃ purekammaṃ bhaṇṇai.
(Da 5.1.32 JiCū p. 178)
