I am very nice to see your question. There are at least 2 elements too deeply understand whole tipitaka, 1. tipitaka in original pāli and 2. strong memorizing that whole tipitaka-pāli.
Your doubt can not clear by word by word translation, but it will clear by deep understand each pāli-word's description.
So, I will give you word by word translation, and a link for each pāli word's description. It looks like commentary and abhidhamma, but the fact is pāli-words link each other by themselves. I just show that pāli-relationship to you:
sabba-pāpassa akaraṇaṃ, kusalassa upasampadā;
Whole-unwholesome-mind (whole 3 akusala-mind-types and whole 5 akusala-mind-factor-types=14 akusala-mind-factors with 13 general mind-factors) is not doing (by practitioner),
Whole-wholesome-mind (whole 4 kusala-mind-types, and whole 4 kusala-mind-factor-types=25 kusala-mind-factors with 13 general mind-factors) is done (by practitioner);
sacittapariyodapanaṃ, etaṃ buddhāna sāsanaṃ.
Own-mind is perfect done to be pure (by perfect practiced arahanta-ariya; arahatta-phala [best magga-kamma's vipāka]),
This every sequence, 3 sequences, is teaching of every buddha.
khantī paramaṃ tapo titikkhā, nibbānaṃ paramaṃ vadanti buddhā;
Khanti, Enduring, is the best of mind-practice (when you break up endure-meditation, the other meditations will finish, too).
'Nibbāna is the best (of all above line)' every buddha said the same.
na hi pabbajito parūpaghātī, na samaṇo hoti paraṃ viheṭhayantoฯ
Especially (for to be a monk), no any the breaking-up person (=monk who is enduring to breaking above whole-unwholesome-mind) hurts the others,
No any the peace person (=monk who is enduring to meditate peaceful path such as above whole-wholesome-mind, arahatta-phala, and nibbāna) attachs the others.
anūpavādo anūpaghāto, pātimokkhe ca saṃvaro;
(Endure to) Don't damn or hurt anyone (by mettā meditation and karuṇa meditation),
(Endure to) observe in (5 types) saṃvara (=4 pārisuddhisīla);
mattaññutā ca bhattasmiṃ, pantañca sayanāsanaṃ;
(Endure to) be a person who (know how to) eat smart in foods,
(Endure to) be a person who (know how to) suffice for furniture;
adhicitte ca āyogo, etaṃ buddhāna sāsanaṃฯ
(Endure to) make an effort to meditate adhicitta (concentration meditation),
This every practice (above) is teaching of every buddha.
