After the Sixth Ancestor Huineng was extinguished, Cao Xi was like a group of dragons without a leader, and he was silent for 20 years. During this period, Shenxiu's Zen learning was continued by Zen masters such as Pu Lin and other Zen masters, and the momentum was very strong, and the two Kyotos of Chang'an and Luoyang in the north strongly advocated the method of gradual enlightenment.

The Sixth Patriarch Huineng followed the teachings of the Fifth Patriarch Hongren, and no longer passed down the Dharma position with magic instruments such as robes and golden bowls, but adopted the method of "passing the heart to the heart". In terms of strict legal definition, there have been no seven ancestors or eight ancestors since the six ancestors of the Tang Dynasty; However, the most powerful divine society in the world is often referred to as the "Seven Ancestors".

The gods will go out to visit, and learn that the method of epiphany was resisted and blocked in the north, and thought: do not enter the tiger's den, but get the tiger, so he is determined to carry forward the great cause of the six ancestors Huineng, and resolutely went north, in the eighth year of the opening of Tang Xuanzong (720 years), Feng Yi lived in Nanyang Longxing Temple, and promoted the Zen law of Nanzong, and the world called him "Nanyang monk" at that time. At that time, the great poet Wang Wei once went to Longxing Temple to ask the gods to consult the Southern Sect Zen method, and was greatly moved, and then wrote the "Six Ancestors Huineng Zen Master Inscription and Preface" to publicize it.

Chang'an and Luoyang, as Kyoto, are in the north of China, and gradually realize that the foundation of the Northern Sect is deep and the power is extremely strong.

With a fearless spirit, the gods will go to Chang'an and Luoyang alone. Vigorously promote the six ancestors Huineng's Dunjiao method, advocate "no thought" as the sect, and promote the theory of "epiphany". When the gods would propagate the Dharma, they lived in the Heze Temple in Luoyang, and set up a monument for Huineng in the temple, and painted the "Six Leaves Map" according to the lineage inherited by the Southern Sect, and the world called it "Master Heze". He has two disciples, the nameless Zen master and the Faru Zen master, who have been following him all the time.

In the twentieth year of Kaiyuan (732), the Shenhui said to his disciples: "Shenxiu's eldest disciple, Zen Master Pu Lin, is the inheritor of the Northern Sect, and he built a monument for Shenxiu, insisting that Shenxiu is the sixth generation patriarch of Zen Buddhism, and he also claims to be the 'Seven Ancestors', vigorously promoting the teachings of various sects, and degrading my Southern Sect to worthless, which is really too deceitful!" It was decided to set up an uncovered conference in the Dayun Temple in the slippery platform of Henan Province to challenge the Northern Sect of Gradual Enlightenment, to set the purpose for the world's Taoists, and to distinguish right from wrong for the world's Taoists.

Faru, a disciple of the Shenhui, frowned tightly, and was a little worried: "Master, although Shenxiu has been extinguished for a long time, this is the territory of the Northern Sect, and everyone in the world says, 'Shenxiu is a sect between the two capitals'." We are alone, under siege, and I am afraid that it will be difficult to overcome them. ”

Another disciple Nameless was also admonishing him: "Master, I heard that the Shandong Chongyuan Zen Master of the Shenxiu Department has a poor eye, and he is a great debater of 'two famous broadcasts in Beijing, overseas knowledge', arguing with others, invincible, and never defeated, we rashly challenge, once we lose, it will backfire, and the prestige of Nanzong will be lost." We need to be cautious!" Facing the persuasion of the two disciples, Shenhui looked calm and said confidently: "During the Three Kingdoms period, Zhuge Liang went to Jiangdong alone, facing many strategists of Wu State, without fear, fighting with Confucianism and winning a big victory, what did he rely on? In addition to relying on eloquent eloquence, it is more important to rely on the truth in hand. I also know that this matter is very important, and now, my Southern Zongdun Sect is the true transmission of the Five Ancestors Hongren, I have the axiom in my hand, the Dharma in my chest, and I should be the winner in my hands, so why be afraid?"

I heard that it was a great debate between the north and south Zen Buddhism about right and wrong, and monks from all over the world flocked to it.

In the sky, the dark clouds are heavy, and it is breathless; But in front of the Dayun Temple, there are a sea of people, and the water is impassable.

In the face of the abuse and siege of many Zen masters of the Northern Sect, the god will stand alone on the high platform, facing the cold wind, his face does not change, like the mainstay of the impact of the waves, and the Shandong Chongyuan Zen master started a great debate.

The gods will claim that they are the official successors of the "Nantianzhu Yiyanzong", and propose that Bodhidharma "pass on a collar robe to give the Dharma to Hui Ke, Hui Ke to pass on the monk Can, Seng Can's letter to preach the Tao, the Tao letter to pass on the Hongren, the Hongren to pass on the Huineng, six generations of inheritance, endless," pointing out that the Nanzong Huineng is the orthodox six ancestors. In front of 10,000 people, he mercilessly pointed out that the five ancestors Hongren did not pass on the robes and golden bowls to Shenxiu, and Shenxiu was not qualified to be the heir of the five ancestors at all. The Northern Sect, which violently criticized Shenxiu, "inheritance is pong, and the method is gradual". The legal system established by Pussa-chan is forged. In front of everyone's eyes, the Chongyuan Zen master who thought he was able to suppress thousands of people was speechless, and the Zen master of the Northern Sect who was speechless was dumbfounded.

The controversy between the two factions of the Dayun Temple Uncovered Conference has become a topic of discussion among the vast number of believers in the north after tea and dinner, and it has spread farther and farther, and it has spread more and more widely. The two major factions of Zen Buddhism, Nantun and North, are bound to become fire and water, and the struggle is becoming more and more intense. But because of the great victory of the Divine Society in this debate, the Buddhism of the Southern Sect rose rapidly in the north; Correspondingly, the Northern Sect gradually declined.

In the fourth year of Tianbao (745), Song Ding, the squire of the military department, believed in the Zen method of "epiphany" in the south and invited the gods into Luoyang, the eastern capital. At this time, the Zen master has passed away, the gods will show their ambitions in Luoyang, vigorously spread the purpose of "epiphany", build a monument for the six ancestors Huineng in Heze Temple, and paint the "Six Leaves Map" according to their own lineage, and say that the six ancestors Huineng is the orthodox heir of the Zen lineage.

Later, the Divine Society compiled the record of the debate and published it as "The Theory of Right and Wrong in the Bodhidharma South Sect".

Due to the "gradual enlightenment" of the Shenxiu faction in the north is extremely prosperous, Luoyang is the center of influence of the Beixiu, and the disciples of Shenxiu have always regarded Huineng, who had been granted by the five ancestors to pass on the holy relics and fled south, as an enemy, so they saw the opportunity, relied on their power, and with the help of the political forces and means they could rely on, launched a fierce and multiple counterattack against the Shenhui, and finally expelled the Shenhui from the capital.

Shenhui was forced to move to Hubei, exiled and tossed, in less than two years, forced to move four times, from Yiyang County to Wudang County, and then to Xiangzhou, Tianbao 13 years (754) July, and then moved to Jingzhou Kaiyuan Temple. During the period of forced eviction, the Shenhui was as ambitious as the arrow, unchanged from its original intention, and everywhere vigorously promoted the "Dunjiao" method of the Southern Sect, and promoted it vigorously.

In the fourteenth year of Tianbao (755), there was a famous "Anshi Rebellion" in history, and An Lushan raised troops to capture the eastern capital Luoyang, approaching Chang'an. Emperor Xuanzong was terrified, abandoned the city, and fled to Xishu. At that time, there were many natural disasters. It was another day of war, which weakened the national strength of the Tang Dynasty and emptied the treasury. The Tang Dynasty is in jeopardy. Deputy Marshal Guo Ziyi adopted the suggestion of the right servant to shoot Pei Mian, and ordered all county governments across the country to set up ordination altars for monks, and collect a certain amount of sesame oil money as tax money as military salary. He invited the God Council to preside over the matter.

At that time, the god who was deeply expected by the public was falsely accused by the traitor Lu Yi, and lived in Jingzhou.
