Visuddhimagga I-111

Yathā pana indriyasaṃvaro satiyā, tathā vīriyena ājīvapārisuddhi sampādetabbā.

（三、活命遍净戒的成就）如根律仪的依于念，而活命遍净戒当依精进而成就。

Ñ(I,111): (c) As restraint of the faculties is to be undertaken by means of mindfulness, so Livelihood purification is to be undertaken by means of energy.

Vīriyasādhanā hi sā, sammāraddhavīriyassa micchājīvappahānasambhavato.

依精进而成，因为善于励力精进者，能舍邪命故。

Ñ: For that is accomplished by energy, because the abandoning of wrong livelihood is effected in one who has rightly applied energy.

Tasmā anesanaṃ appatirūpaṃ pahāya vīriyena piṇḍapātacariyādīhi sammā esanāhi esā sampādetabbā parisuddhuppādeyeva paccaye paṭisevamānena aparisuddhuppāde āsīvise viya parivajjayatā. Tattha apariggahitadhutaṅgassa saṅghato, gaṇato, dhammadesanādīhi cassa guṇehi pasannānaṃ gihīnaṃ santikā uppannā paccayā parisuddhuppādā nāma.

所以精进于行乞等的正求，得以断除不适合的邪求，受用于遍净的资具，得以违避不遍净，如避毒蛇一样，这样便得成就活命遍净戒。

Ñ: Abandoning, therefore, unbefitting wrong search, this should be undertaken with energy by means of the right kind of search consisting in going on alms round, etc., avoiding what is of impure origin as though it were a poisonous snake, and using only requisites of pure origin.
