After the extinction of the Buddha, the twelve parts of Sanzang assembled Ananda, Ye Jia and others and 500 arhats, all written by people from memory. Is it difficult to have no dross?

According to the Buddha's Light Dictionary

First gathering: 90 days after the Buddha's death, under the protection of King Zhao, 500 Arhats gathered in Qiye Cave outside the suburb of King Shehe of Mojeto, and held their first gathering, headed by Mahakaya, so it was called 500 gathering, 500 gathering and 500 separation. This collection was compiled by Ananda (Xiuduoluo or Fazang) and Apo (Pizang) according to Five Points Method Volume 30 and Maha Monk Method Volume 32, and then the elders reviewed and revised the recited scriptures. This statement is generally considered more credible by historians. There are other sayings, such as: According to Volume I of Great Wisdom and Volume I of King Kong Fairy, Ye Jia collected Mahayana Sanzang on Kaoya Mountain, while Manjusri and Maitreya are equal to Tiewai Mountain, and together with Ananda, they collected Mahayana classics, which are called Tieweishan Mahayana Collection. But this theory is suspected to be a legend after the rise of Mahayana Buddhism. (Therefore, Mahayana Buddhism in the Han Dynasty rarely uses this expression, and it is usually the first time to gather in Qiye Cave. )

The second gathering: About 100 years after the death of the Buddha, the Bhikkhu, a postscript ethnic group in eastern India, opposed the precepts and put forward ten new ideas. For this reason, 700 monks will leave the city in Pishe, with Jeshe as the first, and hold a second gathering, which is called 700 gathering, 700 gathering, two gathering and two gathering. This episode is based on the Faji, which stipulates that ten things done by monks in Yi's postscript are illegal.

Third gathering: In 236 years after the death of the Buddha, under the protection of King Ashoka, 1,000 monks will hold the third gathering in Fahrenheit City of the kingdom of Magadha, with Muyilian Di Zi as the first time. This book focuses on classics, law and papers. Emperor Lian's son had to write "On Things" himself to refute all kinds of heresies at that time; After the rally, a group of monks were selected to spread Buddhism outside the Ganges River basin and India. One, two will say that Buddhism has spread in the north and south, and three will say that it has spread only in the south.

Basically, this is a relatively large collection of three times recognized by Mahayana College. Later, Buddhism spread all over the country.

For example:

The fourth party: there are two kinds of sayings: spread to the north and send children to the south. (a) Buddhism spread to the north there are two records:

(1) According to the legend of master Bobandou, 500 years after the death of Buddha, it is said that many monks, Ga Yin Yanzi, went to Kerpin country in northwest India to collect 500 arhats and 500 bodhisattvas, which were written by A?vagho?a Bodhisattva and written into thousands of buddhas (that is, the theory of great bodhisattvas). (2) According to Volume III of the Western Regions of the Tang Dynasty, four hundred years after the death of the Buddha, under the protection of King Ganesha (Van Kaniska), monks and friends from all over the world first gathered in the country of Ganesha Milo (the guest) to explain Sanzang's theory of five hundred people, and first paid tribute to Wu Bo's hundred thousand people. The second time, he made a eulogy on 100,000 poems of Penaye, explaining Penaye's (French) Tibet; After that, he wrote an ode to 100,000 poems by Abidharma Piposha, explaining Abidharma's Tibet. All the 300,000 praises and 9.6 million words, King Ganesiga used red copper as a mirror, carved paper, sealed stone letters and built towers in it. The latter is more credible.

. (2) According to Mahayana, Southern Buddhism said that the fourth gathering was held in Arruga Cave (Aru Temple) in Matri Village during the reign of King Patagamani of Ceylon, presided over by Rohida and attended by 500 monks. During the meeting, I recited the Buddhist Sanzang, revised Sanzang's annotations, rearranged the classical order, and compiled the first annotation of Bali Sanzang and Sinhalatam. Fifth gathering: According to the records in Chapter 6 of the Pali History of Religion and History of Myanmar, 187 1 year, Myanmar King Mindong (reigned 1853 ~ 1878) called 2,400 monks to hold the fifth gathering of Sanzang in Mandalay, the capital. This episode focuses on the collection of dharma books, and it took five months to proofread the similarities and differences of the original scriptures and recite them together. The collected Sanzang characters were carved on 729 square marbles and erected in Kuthodaw at the foot of Mandalay Mountain, surrounded by 45 pagodas, which still exist in the ancient capital of Mandalay. Sixth Collection:1May, 95417th Visakari (World Buddha Day), Myanmar Buddhism held its sixth collection under the sponsorship of the state. The significance of this anthology lies in uniting Buddhists, promoting the prosperity of Buddhism in attendance, and improving Myanmar's status as an independent country. The assembly site is located on Igu Mountain in the northern suburb of Yangon, and the building is modeled after the first assembly of Qiye Cave in India. This episode is based on 729 marble inscriptions carved in the fifth episode, and various Pali versions of Ceylon, Thailand, Khmer, London Pali Scripture Association and Myanmar are widely used for detailed textual research. The assembly is completed and the printing is circulated. The gathering was attended by monks from various countries scattered in the south, and monks from various countries scattered in the north were also invited to watch the ceremony, which lasted for more than two years and was completed on 1956 Vesak Festival (2500 Buddhist calendar).
