This is a VERY important sutta. Evreyone should read it.
In this sutta, the Buddha described in detail these “basics” that one should first undertake, pointing out the bad outcomes of lying, etc, which are nothing other than dasa akusala.
Here is the link to a translation and the Pali versions side-by-side, at the same website that you referred to:
“Advice to Rāhula at Ambalaṭṭhika“.
Translations of some verses are not that good, but the general idea comes through, especially if you take into account the following. Two especially bad translations are for akusala as “unskillful” and kusala as “skillful”. It would be much better to translate them as “immoral” and “moral”. One does not get rebirth in the apayas with unskillful actions, but rather immoral actions.
I just discussed the importance of this sutta under the topic, “Basic mindfulness & sense-pleasures for niramisa sukha?“. You may want to read that too.
