It seems that you have not understood my post correctly. This is my fault, I should
have taken more trouble to explain clearly.
The passage which I quoted was just an example to show the words used. I took one of your
quotes, and edited it. But I was commenting on the whole of MN 117.
starter: "I agree with you that the 'noble path' here means a particular path (Right intention/thought) instead of the whole N8P."
You misunderstood me here. What I meant was that the path from stream entry to
non-returner, which has eight factors, is called the learners (sekha) course (path).
The final part, from non-return to arahant, which has ten factors, is called, in MN 117,
'the noble path'.
starter: " The section for the non-learner (who hasn't understood 4NT) is what I call the mundane path, which aims at the effacement of 10 unwholesome deeds, establishment of the 8 path factors and the understanding of 4NT."
In the four Pali Nikaya's, the asekha (non-learner) is a higher stage than the sekha
(learner). The one who has not yet understood the 4NT is the puthujjana (worldling,
or the ordinary man).
starter: "The section for the trainee (sekha, who has understood 4NT) is what I call the Noble path, which aims at the perfection of the 8 path factors leading to the fruits of Right knowledge and Right liberation ("10-fold path")."
What I would say is this: The section for the trainee (sekha, who has understood 4NT)
is what I call the 'trainee's course', it has eight factors and is the first, and main
part of the noble eightfold path, up to non-returner. Beyond this the path has ten
factors. This final part of the path is called, in MN 117, the noble path.
Because 'this world' has ceased for a non-returner, and he has arisen in the 'other
world', the last part of the path is called 'lokuttara' (world transcending, supramundane, transcendent.)
These are just some ideas, do not worry if they make no sense to you.
Kind regards, Vincent.
