Bodhidharma (date of birth and death is unknown, it is said to be 528-535 AD), a South Indian, the third son of King Xiangzhi (or Brahman or Persian). As the pioneer of Zen in China. Brahman's name is bodhidharma, also known as bodhidharma, Damodolo, Damodolo and Bodhidolo. Commonly known as Dharma (also known as Dharma), the translation is Tao.

The legend of Dharma is hard to distinguish between true and false. According to records, he lived for one hundred and fifty years. The earliest record about him can be found in Galand of Luoyang written by Yang Xuanzhi in the Northern Wei Dynasty (this book was written in Dingmao, Wuding, Eastern Wei Dynasty, in 547 AD). When Buddhism was born cannot be verified. There are different versions about the time of death, such as the second year of Liang Datong (AD 528) and the first year of Liang Datong (AD 535) or two years. In addition to Hui Ke (AD 487-593), there are other disciples, such as Yudao (date of birth and death unknown), Monk Deputy (date of birth and death unknown) and Lin Tan (date of birth and death unknown). There are four lines in the understanding of Buddhism and Buddhism.

According to the Deng Chuan in Jingdezhen (Volume III), Dharma traveled across the ocean to Guangzhou, China in peacetime (520-526 AD), and Emperor Wu sent envoys to meet him in Jiankang, the capital, and went to the palace for an audience. It is also said that after the death of Father Dharma, his disciples buried him in Xiong 'er Mountain in Henan. Three years later, Song Yun, the messenger of the Northern Wei Dynasty, returned from the Western Regions, but met Dharma in Qingling. Seeing him walking alone with sandals in his hand, he told Song Yun that he was going to the Western Heaven. Later generations didn't believe it, so they dug up his grave, only to find that there was only a straw sandal in the coffin and nothing else, so there was a miraculous change of "only returning to the West", which put an end to the legendary life of the founder of Dharma.

Dharma once sat on the wall of Songshan Shaolin Temple for nine years, practicing Mahayana wall view, and was called "Brahman on the wall" by people at that time. Later, 40-year-old Zen master Shen Guang would rather give up his life in order to obtain Buddhism. He stood in the snow for a few days and cut off his left arm to show his desire to seek Buddhism. Finally, he got the Mahayana Dharma of Dharma, taught the Dharma, changed his name to Hui Ke, and became the second ancestor of Zen in China. The inheritance of Zen in China stems from the fact that the Buddha of Lingshan Society taught Buddhism to the smiling Mahakasyapa. Therefore, Ye Jia was the founder of Tianzhu Zen, and then came to Dharma for the second time, accounting for twenty-eight generations. China began to spread Dharma to France, and when the sect was founded, it formed a glorious period of "one flower and five leaves" and "five families and seven sects". Therefore, Buddhism is also known as "the ancestor of Zen" or "the ancestor of Buddhism".

After Dharma arrived in China, he began to preach the Zen method of "two enters and four lines" with the four-volume Lengga Sutra as the main classic, teaching his disciples and enlightening chinese zen; Because its research method is to thoroughly see the origin of the heart and to "spread the seal of the Buddha's heart", Zen is also called Buddhism, Dharma or non-Sect. It can be said that "the second middle school and the fourth line" is the crystallization of Dharma's life's painstaking efforts, the central idea of his theory, and the method by which he teaches the world to practice meditation.

The "two-in-four lines" of Buddhism is also called "four-line view" or "Mahayana wall view" The so-called "two-entry" refers to "rational entry" and "practice entry". The method of "reasoning" is the method of observing from the wall, taking "reasoning" as the content of thinking, mainly "explaining Buddhism by teaching", that is, understanding the truth of Buddhism from the heart through various teaching methods mentioned in Buddhist scriptures, which belongs to teaching thinking and requires abandoning falsehood, returning to truth and dropping in. So reasoning is also called "peace of mind". In order to cooperate with meditation practice, we must also pay attention to "practice", that is, practice according to what we have learned. Basically, there are "four laws", also called "four lines": (1) If people who practice becoming monks encounter pain and suffering, they will repay their bad karma caused by "injustice and hatred" since ancient times. (2) Follow the fate-monks should be able to realize that everything is born by fate, good causes get good results, and evil causes get bad results. Sue has felt the wealth, poverty and honor and disgrace in the world, so there is no need to rejoice or complain. All gains and losses follow fate, no happiness and no worries, and follow the Tao. (3) Nothing to ask for-monks all know that desire is the source of pain and trouble. Therefore, stop greed and delusion, have no greed and love for worldly possessions, and naturally feel at ease. (4) Call for Buddhist practice-practitioners must practice in accordance with the requirements of Buddhism in order to correspond to Buddhism or Buddhism (that is, the principle of "pure nature"), and to get rid of persistent and material fatigue and achieve liberation.

From this perspective, the Mahayana of Buddhism is very obvious. He combined "reason" with "action". It is precisely (Zen) that sets (wisdom) and wisdom. On the one hand, he should "see the Tao"-realize the truth (truth), on the other hand, he should put it into practice-in line with the enlightened truth and apply it to daily life. In short, "entering" belongs to the practice of teaching method, which teaches people to get rid of all love and hate lust and practice according to Buddhist teachings. It should be based on "walking in" and correspond to the "pure natural principle" obtained from the wall landscape. At the same time, it must be combined with "walking in", which is the characteristic of Dharma Zen, that is, the combination of theory and practice.
