The Buddha gave the answer in the classic Shurangama Sutra. That is, "the realm is like an illusion, and now it is from the heart." Simply put, it is "only knowing unbounded". The real world is a world with only spiritual knowledge (Araille's knowledge), and there is no world that ordinary people mistakenly think. To this end, the Buddha preached the teachings of Sanzang and the Twelve Chapters.
The Buddha revealed this truth from two aspects, namely, breaking and making up for the loss.
Open circuit gain:
The world that ordinary people perceive by themselves is actually just an illusory scene revealed by their own mind (Araya's knowledge), and this seemingly real world does not exist. However, ordinary people stubbornly regard the appearance of the heart as a real existence independent of the heart, which is only imposed by ordinary people's ignorance. This error is called gain. In order to get rid of and correct this mistake, the Buddha's knowledge is to break the profit. Agama, which was preached at the beginning, mainly broke the gain of "people insist on themselves" The second transmission of the Prajna Sutra mainly broke the harvest of "obeying the law".
Compensation and reduction:
Ordinary people make a mistake once and make a second mistake. That is, ordinary people can't see or admit the true state witnessed by saints (buddhas and bodhisattvas on the ground) and lose the true state in the hearts of ordinary people. This kind of mistake is called reducing losses. Saints have the real realm witnessed by themselves, which ordinary people can't see or admit, which reduces the authenticity. In order to get rid of and correct this mistake, the Buddha called it compensation and reduction. The third reading is mainly to make up for the loss. There are mainly Jie Shen's Secret Land, Lengga Land, Secret Land and Flower Land.
When the Buddha was a generation, he only taught two things: breaking and making up for the loss. The gains and losses of ordinary people are two mistakes made at the same time. Because ordinary people have gains and losses, the Buddha called us ordinary people "dreaming". Ordinary people think that the cognizable mind is separated from the cognized foreign object, and they are obsessed with the foreign object. Stick to this cognitive model, and the result of this gain error is that you can't see the true state witnessed by the saints. Because the true state witnessed by the saints is not perceived by the senses of ordinary people. Ordinary people are unexpected and incredible, that is, the so-called "words and deeds, the heart is destroyed."
The purpose of the Buddha's lecture is to get rid of our ordinary people's interests, and at the same time the real realm will naturally appear. Therefore, the focus of Buddhism is to cut off profits, and we have to wake up to see that the really important way to study is to cut off profits.
If ordinary people want to see the real state, they should get close to Buddhism, smell Buddhism and express bodhicitta (consciously, feel him and feel complete). Only by intensive reading according to Buddha's instructions can you be admitted. After entering the ground, Zheng continued to practice in the "ten places" and finally became a Buddha with wide feelings.
