Нирвана архатов в Саддхарма пундарике и Абхисамаяламкаре (неокончательная нирвана)

Right after the death-mind, [those socalled
Arhats] take birth in the crevices of lotuses in pure
Buddha-fields in the realm without outflows. Then, as the
scriptures make clear, they are awakened by the sun rays of
the perfect Buddha Amitabha and so on in order that they
will remove the undefiled darkness, produce the thought of
enlightenment, in the course of their liberation go through
lives that are like a journey through hell and so on, and
gradually equip themselves with the two accumulations
and become teachers of the world. So, by stopping the cankers
that cause rebirth [those Arhats] stop birth in the resulting
triple world, but [they do not stop] birth in the realm
without outflows, [i.e., they do not stop the capacity for a
Bodhisattva's compassion that causes birth in the world for
the sake of others].

Those who are scared of [cyclic existence obtain the two
enlightenments and satisfied with the finishing of life are
called those who have reached nirvana. But (hey do not have
nirvana, because, even though they are not born in the three
realms of  cyclic  existence they live in the realm without
outflows. Later the Buddha has awaken them in order to
remove undefiled ignorance, and they equip themselves
with the accumulations for enlightenment. They too become
leaders of the world.

Translated into English by Burton Watson
"The Buddha knows that the minds of the living beings are timid, weak and lowly, and so, using the power of expedient means, he preaches two nirvanas in order to provide a resting place along the road. If living beings choose to remain in these two stages, then the Thus Come One will say to them, 'You have not yet understood that is to be done. This stage where you have chosen to remain is close to the Buddha wisdom. But you should observe and ponder further. This nirvana that you have attained is not the true one. It is simply that the Thus Come One, using the power of expedient means, has taken the one Buddha vehicle and, making distinctions, has preached it as three.'

Translated into English by the Buddhist Text Translation Society
If living beings only hear of the One Buddha Vehicle, they will not wish to see the Buddha or to draw near to him. Instead, they will think, 'the Buddha path is long and far; it can only be accomplished after much labor and suffering.' The Buddha knows their minds to be weak and lowly. When they are half-way there, he uses the power of expedients to speak of the two Nirvanas in order to give them a rest. If living beings dwell on these two levels, the Thus Come One then tells them, 'You have not yet finished your job. The level you are dwelling at is near the Buddhas' wisdom. You should observe and ponder this: the Nirvana you have attained is not the real one. The Thus Come One has but used the power of his expedients and, within the One Buddha Vehicle, discriminated and spoken of three.'

Перевод с китайского и комментарии Александр Николаевич Игнатович
Если живые существа только слушают Одну Колесницу Будды, [они] не хотят видеть Будду, не хотят приблизиться [к нему], думая: "Путь Будды длинен и долог, [мы] сможем пройти [его, лишь] затратив много труда и перенеся множество страданий". Будда, зная, что у этих живых существ дух слаб, а мысли ничтожны, с помощью уловки дал [им] отдых посредине пути и проповедовал о двух нирванах (Две нирваны. Имеется в виду нирвана "с остатком" и нирвана "без остатка"). Если живые существа будут пребывать на [одной из] двух ступеней (Две ступени. Имеется в виду достижение живыми существами состояния шраваки или состояния пратьекабудды.), тогда Татхагата скажет им: "Вы еще не достигли конца. Состояние, в котором вы пребываете, близко к мудрости Будды. Посмотрите и поразмышляйте! Нирвана, которую [вы] обрели, неистинная. Татхагата только с помощью силы уловок выделяет в Одной Колеснице Будды три и проповедует [их].

Right after the death-mind, [those socalled Arhats] take birth in ... pure Buddha-fields in the realm without outflows. Then, ... in the course of their liberation go through lives that are like a journey through hell and so on, ...and become teachers of the world. So, by stopping the cankers  that cause rebirth [those Arhats] stop birth in the resulting  triple world, but [they do not stop] birth in the realm  without outflows

В голову приходит только Суддхаваса у тхеравадинов, где находятся анагамины, и личности уровня арахаттапхалаттха и арахаттамаггатха. Выход оттуда, считается, только один - париниббана.

Кстати (старая мысль), если исходить из идеи, что наш мир с точки зрения будды - чистая страна, которая нами только воспринимается как плохой мир.

То ничего не мешает интерпретировать рождение в "чистой стране", как обычное рождение со страданием и так далее ничем не отличающимся от нашего обычного мира с кочками и ямами.

Не подходит так как должен быть выход (чтоб учить существ), во-первых, и архаты туда не попадают, во-вторых.

Обещают отличный мир, но оказывается - надувательство?

И первое и второе - оно довольно таки странное.
