A Buddhist dictionary: "This is a common phrase to explain why a vacuum cannot be obtained without treatment, so as to get rid of the obsession with Jaken. This term or concept is often used by Sanlun Sect and Zen Sect to attract scholars. The so-called four sentences usually refer to four sentences such as "yes", "no", "yes" and "no", or "yes", "no" and "neither" as the general form of judgment. In the Zen forest, it also refers to the four materials of Yi Xuan: (1) taking people without taking territory, (2) taking territory without taking people, (3) taking people without taking territory, and (4) taking people without taking territory. In addition, Wei's Selected Works of Mo Jing holds that there are as many as ten kinds of four sentences. All faults refer to all negatives, such as Tathagata Nirvana mentioned in Volume 21 of Kitamoto Mahayana Sutra, which means all kinds of negatives, such as non-existence, absence, doing something, not leaking, not leaking, and even non-past, non-future and non-present. Therefore, based on all judgments and discussions, we can see that all four sentences are pseudonyms. But the ultimate goal of Buddhism is to transcend these pseudonyms and reach the realm of worrying about death. Therefore, Zen forest rumors are famous for' four sentences are absolutely wrong'. There are many cases about four hundred mistakes in Zen so far, which is a guide to Zen. 【 Kitamoto Mahayana sutra volume three vajrayana body, Chinese theory volume twenty, Mahayana theory volume one, Jing Zong volume forty-six, blue-eyed record seventy-three 】 "
