Conventional truth is further divided into "proper secularity" and "inverse secularity"

The phenomena of all dharmas seen by ordinary people in secular truth are "reverse secularity", which is the "famous worldly quantity" "For example, the world of Saha in the worldly truth seen by ordinary people is a dirty land. The phenomena of all dharmas seen by saints in conventional truth are "correct secularity", which is the "pure view of famous sayings". For example, the Saha world in conventional truth seen by Buddhas and Bodhisattvas is a pure land.

There is this passage in "Vimalakīrti's Sutra": Once, Sakyamuni Buddha preached when teaching: If all Bodhisattvas want to feel the purity of the external environment, they should purify their minds. . If the mind is pure, the external environment will be pure. When the mind is pure through practice, the external environment will also become pure. At that time, Sariputra was also with the Buddha. He thought to himself: The Saha world is so impure, is it possible that the heart of Sakyamuni Buddha is still not pure? After the Buddha learned of his thoughts, he asked Sariputta: I am blind and cannot see the sun and the moon. Is this the fault of the sun and the moon, or is it the fault of the blind man? The relic replied: It is the fault of the blind man, not the fault of the sun and the moon. Because a blind person has no eyes, he cannot see the sun and the moon, not that the sun and the moon do not exist. The Buddha also said: The true nature of the Saha world is always pure, but ordinary people are like blind people, always unable to see.

At this time, a Bodhisattva who came to the Saha world from other Buddha lands to listen to the Dharma said: The Buddha land I see now is pure. Shariputra disagreed and retorted: This Buddha land is impure! So the two of them started a heated debate.

Just when it was difficult to distinguish, the Buddha used his supernatural power to reveal the true face of the Saha World. Everyone present witnessed it with their own eyes: the Saha World is just like the Western Paradise and other Buddha lands, very pure. solemn. Afterwards, the Buddha told the public: My world itself is like this, and it will always be like this, but you don't see it.
