In Mahayana, Pure Land are usually depicted as a Reward Land. Each Buddha, after his enlightenment, create his own Pure Land according to their merits.
In the Trikaya theory, the Enjoyment Body has a beginning, but not an end. Following this logic, an Enjoyment Land, which is Pure in nature, a Realm of the Buddhas, will never decay or become in Impure, because it is created by each Buddha merit and mind.
Different Masters explains this Enjoyment Lands as outside Samsara and Triple Realm, even when Sutras describes the Pure Lands as "earthly" worlds, with beginning and with an end.
The Akshobhya Sutra, explain how will be Decline of the True Dharma in his Pure Land with the following words:
A Treasury of Mahāyāna Sūtras: Selections from the Mahāratnakūta Sūtra pag. 332 wrote:"Sariputra, after the extinction of the true Dharma, there will be a great light illuminating all the worlds in the ten directions, and all the earths will quake, making a great sound. However, [you should know that] the true Dharma cannot be destroyed by the celestial demons, nor will the Tathagata and his disciples pass into oblivion of their own accord. [b]It is because people of that time will lack interest in learning the Dharma that those who can expound the Dharma will go away form them. Hearing little of the true Dharma, the people will become more incredulous, and as a result, they will not strive to practice the Dharma. Seeing the indifference of the people, monks well-versed in the Dharma will naturally withdraw into seclusion and preach the Dharma no more. In this way, the subtle, profound teaching of the Buddha will gradually disappear.[/b]"
Reading this fragment, if the Pure Lands like Amitabha, Medicine Buddha and Akshobhya were described as Outside Samsara and beyond Triple Realm, described as Enjoyment Lands, without death, how can be that the Dharma will decline in such lands? How can it be possible? We are talking about a Buddha Land, a Pure Land created by merits, how can beings there loose faith and contribute to a Dharma end? I can believe in this land a Dharma end is possible, but it's difficult to think in a Pure Land declining.
In the Lotus Sutra it is the same, different Pure Lands are described in this way, with a Dharma ending age.[/quote
In order to understand the old descriptions of pure lands, we must, because we are modern minded humans, put them into a relative framework.
If not, then we can also believe Zeus lives on Mt. Olympus?
Humans have two eyes and cannot see the 4th dimension of infinite space time. If we could see an objects ,"front, back, top, bottom, sides, and insides and all points of references" simultaneously, we'd be in the 4thD. https://www.khanacademy.org/science/cos ... observable
If there was some conscious essence after our physical death, because of the expansion in the 4th dimension this energy would soon be stretched out. It would lose coherence in the vastness of infinite space time.
Energy is finite. This earth is finite. One day all life on this planet will be dead. No one to read or understand
The Dharma. However, the truth of the Dharma is infinite. Therefore it is endless in it's merit.
