In Buddhism, the main purpose of Jian Zhen's eastward journey is to popularize Buddhism and teach laws and precepts. The activities of Japanese monks in Jian Zhen for more than ten years have achieved this goal. Due to the emperor's attention, Jian Zhen was awarded the title of "Big Monk Capital" and became the "ancestor of canon". "Since then, Japanese laws and regulations have gradually become stricter and passed down from generation to generation, all over the world." Tang Zhaoti Temple, built in Jian Zhen, became the Japanese Grand Temple. Most of the Buddhist scriptures in Japan were handed down by Baekje monks, and there are many mistakes and omissions. In the case of blindness, Jian Zhen corrected the mistakes and omissions in Japanese Buddhist scriptures with amazing memory. Because Jian Zhen also made considerable research on Tiantai Sect, Jian Zhen also played a great role in the spread of Tiantai Sect in Japan. Jian Zhen put Japanese Buddhism on the right track, which facilitated the government to control Buddhism, put an end to all kinds of disadvantages caused by neglect of management, and promoted Buddhism to be determined as the national religion of Japan. Jian Zhen and his disciples founded the Du Nan Legalist School, which has become one of the six schools, and still has a bright future today.
Medical aspects
Jian Zhen is familiar with medical prescriptions. When Empress Guangming died, only Jian Zhen's prescription was effective. According to Japanese Notes on Materia Medica, Jian Zhen can distinguish the types and authenticity of herbs by smelling them with his nose. He also vigorously spread the knowledge of Zhang Zhongjing's Treatise on Febrile Diseases, leaving a volume of Master Jian's Secret Recipe. Therefore, he is known as "the ancestor of Japanese traditional Chinese medicine". According to Yasuhiro Nozaki, chairman of Hanfang Nozaki Pharmacy in Japan, the following 36 kinds of herbs were brought from Jian Zhen to Japan for promotion and use: Herba Ephedrae, Herba Asari, Radix Paeoniae Alba, Radix Aconiti Lateralis, Radix Polygalae, Radix Astragali, Radix Glycyrrhizae, Radix Sophorae Flavescentis, Radix Angelicae Sinensis, Radix Bupleuri, Rhizoma Chuanxiong, Radix Scrophulariae, Radix Rehmanniae, Perillae, Radix Salviae Miltiorrhizae, Scutellariae Radix, Radix Platycodonis, Inula, Rhizoma Atractylodis
calligraphy
Jian Zhen and his disciples also have profound attainments in calligraphy. On his sixth trip to the East, he brought Wang Xizhi's original running script, Wang Xianzhi's original running script and 50 volumes of other calligraphy works. This greatly promoted the formation of Japanese calligraphy. Jian Zhen himself is also a famous calligrapher, and his Invitation Book is regarded as a Japanese national treasure.
Architectural aspect
Many of Jian Zhen's Du Dong disciples and followers are proficient in architectural technology. Under the design and leadership of Jian Zhen, the famous Tang and Zhao Temple was built. The lobby building in the temple, facing south, is seven rooms wide and four rooms deep, with a three-story bucket arch shape. It is a Buddhist temple on the top of a hill with a single eaves. Japan's comments on specially protected buildings and national treasures are as follows: "Jintang is the largest and most beautiful building in the balance era." Because the monks in Jian Zhen adopted the most advanced construction methods in the Tang Dynasty, this building is very strong and exquisite. After 1200 years of wind and rain, especially the test of 1597 Japanese earthquake, Dujintang is intact and still stands in Zhao Ti Temple in Tang Dynasty. Jintang has become one of the most valuable and precious objects to study and understand the ancient architectural art in China.
carve
Jian Zhen and his disciples also left a valuable legacy in sculpture. Jian Zhen is accompanied by Buddha statues, but in Japan, many Buddha statues are created by "dry painting" (also known as "clip painting"). There are famous statues of Lushena sitting Buddha, Tathagata and Guanyin with a thousand hands in Jintang of Zhao Ti Temple in the Tang Dynasty. This method appeared in China as early as the Eastern Jin Dynasty, and reached a high level in the Tang Dynasty. During the reign of Wu Zetian, the giant Buddha shaped by clip method was as high as 900 feet. Jian Zhen and his disciples popularized and developed this sculpture art in Japan. In Jian Zhen's later years, disciple Renji and others made a sitting statue with a height of 80.04 cm to commemorate the China monk. Jian Zhen sat cross-legged with his eyes closed, and his thoughts were quiet and realistic. It not only reproduces the true image of Jian Zhen, but also deliberately depicts his spiritual temperament, with fortitude in tenderness, seriousness in serenity and meditation in smile. This Buddha statue was enshrined in Zhao Ti Temple in the Tang Dynasty.
Brother Jian Zhen is honest. What he knows, of course, spread to Japan! The above is his contribution, of course, spread to Japan without any concealment.
