From: Maha-cattarisaka Sutta: The Great Forty
"Of those, right view is the forerunner. And how is right view the forerunner? One discerns wrong view as wrong view, and right view as right view. This is one’s right view. And what is wrong view? ‘There is nothing given, nothing offered, nothing sacrificed. There is no fruit or result of good or bad actions. There is no this world, no next world, no mother, no father, no spontaneously reborn beings; no contemplatives or brahmans who, faring rightly & practicing rightly, proclaim this world & the next after having directly known & realized it for themselves.’ This is wrong view.
"And what is right view? Right view, I tell you, is of two sorts: There is right view with effluents, siding with merit, resulting in acquisitions [of becoming]; there is right view that is noble, without effluents, transcendent, a factor of the path.
"And what is the right view with effluents, siding with merit, resulting in acquisitions? ‘There is what is given, what is offered, what is sacrificed. There are fruits & results of good & bad actions. There is this world & the next world. There is mother & father. There are spontaneously reborn beings; there are contemplatives & brahmans who, faring rightly & practicing rightly, proclaim this world & the next after having directly known & realized it for themselves.’ This is the right view with effluents, siding with merit, resulting in acquisitions.
"And what is the right view that is noble, without effluents, transcendent, a factor of the path? The discernment, the faculty of discernment, the strength of discernment, analysis of qualities as a factor for awakening, the path factor of right view[1] in one developing the noble path whose mind is noble, whose mind is without effluents, who is fully possessed of the noble path. This is the right view that is noble, without effluents, transcendent, a factor of the path.
We know that having wrong view leads to wrong liberation, so the opposite of those wrong views, here I shorten it as mundane right views are needed basically when you reject wrong view, you get right views.
Yet, the mundane right views are described as with effluents (waste), siding with merit, resulting in acquisitions (of becoming/ leading to rebirth).
And the supramundane right views doesn’t seem to mention kamma and rebirth.
So can secular Buddhists somehow use this as an sort of escape route? As long as they don’t commit to rejecting rebirth and kamma (so no adherence to wrong views), could they just by using supramundane right views attain to stream winner?
To be clear, I am not talking about after stream winner attainment, but before.
