Dharma exists for how long?

In Chapter 10, Sub-Product, Vinaya (bhikkhus Indacanda services) has  mentioned that sheMahapajapati Gotami  went to Buddha monk ordained nuns ask, and He only if she agreed to allow France received eight awards. Then, he said to Elder  Ānanda :

- Ananda, if women who do not achieve the ordained left the homeless living in France and Tathagata Law was announced, Ānanda, of dignity, can be long-lived, Dharma can survive a thousand years. Ānanda, because women who have left the monastic life in France and not the Tathagata Law was announced, Ānanda, now the holy will not survive long, Ānanda, France will survive now St. at only five hundred years.

So, today, in 2500 n years does after Buddha PARINIRVANA, many people pessimistic that we're in the Dharma Ending Age, no one can achieve further enlightenment. However, Note and Note Vinaya explain the rise in costs: 1000 years of Dharma refers to the cessation of the contraband or the achievement of four Tue Analysis. Since then 1000 years of the cessation of illegal or pure insight, 1000 years of attainment Real Lai, director 1000 Best Mixed fruit, fruit 1000 years of religion in Save. Thus, Dharma will survive 5000 years, and then no one in the realm who can enter the holy liberation. In addition to this, bhikkhus Dhammanando (Temple Benchmabophitr, Bangkok) said in the Explanatory Note and the Central School has scored another figure: the director's period Arhat results can last up to 4,000 years, then then slowly decline.

Anyway  go again, we should also note that in his final teachings Subhada before passing away, Buddha declared when the Eightfold Path is practiced and preached the right way this world is not never empty the holy attainment (University of PARINIRVANA, the School).END=NAM MO AMITABHA BUDDHA.( 3 TIMES ).VIETNAMESE TRANSLATE ENGLISH BY=THICH GIAC TAM.THE MIND OF ENLIGHTENMENT.VIETNAMESE BUDDHIST NUN=GOLDEN AMITABHA PURELAND=AUSTRALIA,SYDNEY.12/10/2016.
