The Venerables might be busy or hindered. Assuming that taking leave here is welcome, my person takes leave, looking forward that the Venerables will assist in proper explaining as soon as possible.
Nyom
Cheav Villa , as told before Dhamma is all about cause and effect of which is not total determined but can always be corrected in the present. That is one thing. If we miss out this, there is less motivation for putting an effort, here in maintaining something that has arose.
So generally my person does not like certain explainings by certain branches, which follow a kind of timeline found in the commentaries. If remembering right, they say that "we" live already in a time where the highest attainment is Sotapanna.
If following such predictions, and assume that when there is no more Arahat within the Sangha, who acts as Nissaya, it would be actually the case that the Savaka Sangha within the conventional Sangha of Bhikkhus already had died out according the timeline and the end of Arahataphala, many many years, centuries ago, at least a Sangha where Arahat are present.
The underlying justification here is, that a lower could hardly train another higher then himself. And if we look at Vinaya, instructor and teacher, next to other qualifications, would need to have conducts like an Arahat.
That is possible the reason why in most areas of SEAsia, incl. Cambodia, people at broad, incl. monks, assume that there are no more Ariya-puggala within the Sangha (meaning also in the world for them).
That would be a very demotivating situation and is actually also the reason why popular teacher focus on next worlds for attainings rather to motivate for effort right here and now.
As non-action, especially in regard of Sila, Samadhi, Panna, i.e. renouncing, leaving home/stand, is most harmful even for a good in the world, it's in no way useful to maintein a perception of "no more" or "no more possible", but the other extreme of "we have another 2500, or what ever long time, time" actually leads to the same inaction and lazyness. In any case, the most secure bet here is always, at any time, even if all seems perfect here, "this is the last change".
That's the "psychology" and drive found all over the teachings of the Buddha. When "enemies" are not seen, when dangers are not seen, when the hair on the head does not burn, no effort for a better or beyond would be made. If in a stage of ease and not an Arahat, one may be sure that this is the lure of Mara "don't worry".
So at first place the Buddha or a wise teacher, guide, would always point and remind on decay, suffering, insecurity, even then when all seems fine.
Who ever teaches the first or the second view causes "Dhamma-danger" gives many food for turning toward inaction or to focus on worldly attainments. In German such would be called "Teufelskreislauf" which could be translated to "Mara-spiral".
This is the reason why we don't find much on determined predictions in dependency of just time. Yet what we know and can trust is, that all Sang/kharas have an end.
Here now is the point where food for
pāsāda need to be placed to move, seeing the back burning and the most evident sign for "hope" is a gained perception of refuge, Sangha.
That lead now to the need to remember that the "world of reality" is different for every person, being.
For a person who has rightly gained the perception of the Savaka Sangha, this world here and now isn't void of such a Sangha. Having gained, by right touch, the perception of an Arahat, of Arahats, ones world isn't void of Arahats.
So let my person stop here with the more importand question whether Nyom has already met, has met the Savaka Sangha, possible an Arahat, already, so that she has already a clear perception. Has she?
If so, this, her world, isn't empty of Savaka Sangha yet, is not void of Arahats, but that is total not for sure for her possible next world. She could come back and would neither find desired or already gained relatives or parents.
That is why the focus should be not on "is" or "is not" but on "become" and "maintain already gained.
So maybe Nyom likes, after having read and investigate till here, to answer and give account, tell if that is clear till this stage.
