Why does the Buddha blame Ananda asking him to remain living forever?

The Buddha did give the hint to Ananda 3 times about His PariNibbana, but Ananda didn't get it. By the time Ven. Ananda recognized his error, it was already too late for Mara already came and requested the Buddha to go to PariNibbana right after He told Ananda. See DN 16's The Third Chapter of Recitation: 17. Ananda's Failure for more details. Actually the entire DN 16 is a great sutta worth reading from start to end.

Nyom Karen,

Aside of the useless duration extent discussions, to the point: real independent teaches have to be asked timely to stay, since it's not his duty to teach but actually a burden and of no use if others do not desire. Asking serious meant to ask three times to be sure that one has certain resolve toward gaining something and not just acting in moods or out of boredom.

Since Ananda was to foolish to ask at proper time to stay, he is called the one who failed. Many of you might know similar situations of lack doing things at proper time, later run arround facing the results.

Oneself is the ones who votes and seeks for Maras easy play to make the reality of decay his portray of being the one with real power.

The misery and gospels of the Bind Guardians...

[This, being a leson on Dhamma, is not given for trade, exchange, stackes... for wordily purposes and should be possible deleted if the enviroment does not provide toward liberation]

Ananda was possessed by Mara when the Buddha asks him three times whether to extend his lifespan. Ananda remained silent all three times. The Buddha would have known that Ananda was possessed by Mara.

Maybe the Buddha did this so that later on when Ananda asks him to extend his lifespan, Ananda is not grief stricken when the Buddha says that he must attain Parinibbana, since Ananda was the one who enabled it in the first place. So he might feel more of guilt than grief

1. aeons

   It's not aeons, not living forever. It's living only until Buddha's old 100 years.

   Rhys David:

   kappa (adj. n.), anything made with a definite object in view

   So, the translation should be something like this:

   "O Lord! May the Blessed One remain, O Lord! May the Happy One remain, O Lord, throughout the defined median age (Buddha defined it in DN14, AN 7.70).

   Kappa in DN 16 (Kappāvasesaṃ) means the defined median age of Gotama Buddha.

   Kappa in AN 5.23 (PubbenivāsānussatiÑāṇa) means the defined age of the universe's occurrence cycle (from Brāhma's Veda which derived from Anāgāmi Brahma of KassapaBuddha, previous Buddha).

   Kappa in AN 4.156 (AsaṅkheyyaKappa) means the defined uncountable years of each procedure in the universe's occurrence cycle (4 procedures per 1 cycle).

   See the defined median age in Tipitaka:

   DN Mahāvaggo MahānidānaSutta:

   Vipassī lived for 80,000 years. Sikhī lived for 70,000 years. Vessabhū lived for 60,000 years. Kakusandha lived for 40,000 years. Koṇāgamana lived for 30,000 years. Kassapa lived for 20,000 years. For me these days the life-span is short, brief, and fleeting. A long-lived person lives for a century or a little more.

   KN Buddhavaṃsa, 24 Buddhas foresaw:

   Gotama Buddha's age is 100 years old.

   KN Buddhavaṃsa, our Buddha said:

   Even though my age is 100 years old and lesser than the other Buddha, I can let many people enlightened, too.

   

   ***Search "vassasataṃ" and "vassa sataṃ" here. I will not post the search result direct link because it maybe overuses of a website resource.*

   Atthakatha described the same.

2. the Buddha blames Ananda for not requesting that the Buddha lives until touch the defined median age, three times. he had only asked him twice.

   Buddha asked Ānanda only 1 time per question after Ānada request the Buddha three times. Buddha's questions are:

   1. Do you have faith, Ananda, in the Enlightenment of the Tathagata (who has already renounced his will to live on)?
   2. Then how, Ananda (who accepted in the Enlightenment of the Tathagata), can you persist against the Tathagata even up to the third time?
   3. And did you believe in what you said that you have heard and learned from the Blessed One "'Whosoever, Ananda, has developed, practiced, employed, strengthened, maintained, scrutinized, and brought to perfection the four constituents of psychic power could, if he so desired, remain throughout a defined median or until the end of it. The Tathagata, Ananda, has done so. Therefore the Tathagata could, if he so desired, remain throughout a defined median or until the end of it.'"", Ananda? So, they are not the same question.

3. Why does the Buddha blame him ?

   Buddha blames him in the second question because of the first question. Ānanda already memorized DN29, so he knows that the Buddha can't change his decision renouncement. If the Buddha didn't ask him, people will misunderstand "Ānanda, Sotāpanna, can doubt in Buddha". But after Buddha asked b.h.Ānanda by the second question, people will understand right "Ānanda, Sotāpanna, didn't ask Buddha because of the doubt, but he asks because he trusts in both Buddha's speeches (renouncement and DN29) and tried to let Buddha does follow the DN29". By the second question, people will not misunderstand in Ānanda.

See DN29:

From the night when the Tathagata understands the supreme perfect awakening until the night he becomes fully extinguished—through the natural principle of extinguishment, without anything left over—everything he speaks, says, and expresses is real, not otherwise.

That’s why he’s called the ‘Tathagata’.

4. And the Blessed One answered,

   saying: "Enough, Ananda. Do not entreat the Tathagata, for the time

   is past, Ananda, for such an entreaty."

   As I quoted DN29 above that Buddha can't change the renouncement.

I cannot provide a definitive answer however the impression is the Buddha tested Ananda to show the Buddha had achieved His mission; which was to fully establish the Sangha and to fully teach the Dhamma. Since Ananda did not immediately respond with urgency when the 80 year old Buddha dropped the hint to Ananda, it demonstrates Ananda was inherently content with the Dhamma teachings provided.

As for the word 'kappaṃ', it obviously does not necessarily mean "forever". According to the Pali dictionary and according to DN 16, it simply means "a very long time".
