I interpretate this otherwise. Many sutta’s describe something like this:
“And how, bhikkhus, does a bhikkhu who is diligent develop and cultivate the Noble Eightfold Path? Here, bhikkhus, a bhikkhu develops right view … right concentration, which is based upon seclusion, dispassion, and cessation, maturing in release. It is in this way, bhikkhus, that a bhikkhu who is diligent
develops and cultivates the Noble Eightfold Path.” (see Maggasamyutta, SN45).
The Noble Path is based upon seclusion, dispassion and cessation, meaning, here and now.
Dispassion is not something that is absent or something that lies in the future to be gained. Like many teachers say, the goal is present. This is because passion and formations are something that always arises and ceases and is of an adventitous nature. One must understand this to develop correctly (AN1.51). If one takes ones situation like this that one is always passionate then, i feel, one takes a wrong start. I feel those sutta’s of AN1.51 say this.
Also about the holy life it is said:
“For, brahmin the holy life is lived with Nibbana as its ground, Nibbana s its destination, Nibbana as its final goal”(SN48.42, Bodhi)
Another way the sutta’s talk about this is that the enlightment factors, the powers, the qualities have the Deathless as its ground (see SN48, for example).
I interprete this as: they do not have a personal disposition as there ground. They are not grounded in habits. They are not grounded in reactivity, in patterns, in inclinations. They ground in the uninclined.
For example, one might have been grown up in a culture in which the belief in rebirth is very accepted, common, habit-like, or not, but that has nothing to do with the right view of the Noble Path based upon seclusion, cessation, dispassion etc. This Noble Path does not depend on cultural ideas or how one is educated or how one is raised. There is a ground that is not influenced by that.
I feel, interpretation deviate because some feel that the goal is not present yet. Everything must be gained. They do not see or feel that the uninclined, signless, dispassion is not absent and is not something to gain but to uncover. I think that the Dhamma-eye means one sees and knows that it is not absent and not something to be gained in the future.
For me, MN117 is not some strange sutta. I feel it is in line with the rest of the sutta’s. What must be distinguised, i feel, is a path of merit which the Buddha teaches: such as developing good intentions, abandoning wrong views (materialism), etc, because those are not helpful to discover and see the Noble Path based upon dispassion and enter the stream.
It is not like the path of accumulating merit is the same as entering the stream. The stream refers to the Path that is here and now based upon dispassion, seclusion, stilled formations.
