Ennin (by Jnn)

Ennin (c. 793-864 CE, posthumous title: Jikaku Daishi) was a Japanese Buddhist monk of the Tendai sect who studied Buddhism at length in China and brought back knowledge of esoteric rituals, sutras, and relics. On his return, he published his celebrated diary Nitto Guho Junrei Gyoki and became the abbot of the important Enryakuji monastery on Mount Hiei near Kyoto and, thus, head of the Tendai sect.

Tendai Buddhism had been introduced to Japan by the monk Saicho, also known as Dengyo Daishi (767-822 CE). Based on the teachings of the Chinese Tiantai Sect, Saicho’s simplified and inclusive version of Buddhism grew in popularity, and its headquarters, the Enryakuji complex on Mount Hiei outside the capital Heiankyo (Kyoto), became one of the most important in Japan as well as a celebrated seat of learning. Ennin became a disciple of Saicho from 808 CE when he began to study at the monastery, aged just 14.

Travels to China

Ennin was selected as part of a larger Japanese embassy led by the envoy to the Tang Court, one Fujiwara no Tsunetsugu, to visit China in 838 CE and study there. The main aim was for Ennin to study further the Tendai doctrine at the T’ien-t’ai shan. Ultimately, he would stay there for nine years, studying under various masters and learning in greater depths the tenets and rituals of Buddhism and especially the mysteries of Mikkyo, that is esoteric teachings known only to a very few initiated priests.

In China Ennin was initiated by three different esoteric masters, going beyond the level of any previous Japanese monk.

On arrival at Yang-chou and awaiting to be taken to T’ien-tai shan, the monk wasted no time and there and then found priests to teach him shitan, the Indic script used in esoteric texts. He also made his own copies of such texts and underwent an initiation with a priest called Ch’uan-yen. As it turned out Ennin did well, for by the time the Chinese authorities had organised his transport to his original destination he was informed there would be no time to do so if he were not to return to Japan as planned with the embassy. Ennin decided to stay and passed the winter at a monastery in Shantung run by Korean monks. 

In the spring Ennin set off for Wutai, an important pilgrimage site and home to some more learned monks who could help satiate his thirst for Buddhist knowledge. Mount Wutai, where the bodhisattva Manjusri was thought to have appeared, was also a centre of esoteric cults. Over the next 50 days, Ennin acquired such techniques as rhythmically chanting the name of Amida Buddha and changing the intonation each repetition.

From 840 to 845 CE Ennin then studied at Ch’ang-an, learning more of Mikkyo, copying texts and mandalas, and being initiated by three different esoteric masters, going beyond the level that the recognised Japanese master and foremost expert Kukai had reached. In 845 CE Ennin, like many Chinese monks, suffered the persecution of anti-Buddhist emperor Wu-tsung, and he was compelled to return to Japan. This was easier said than done and it took two years, the death of Wu-tsung, and a general amnesty for him to finally find a ship that would make the voyage.  

Ennin’s Travel Diary 

Ennin wrote his now famous account of his time in China, the Nitto Guho Junrei Gyoki ('Record of Pilgrimage to China in Search of the Holy Law'). The monk describes the difficulties and dangers of crossing the sea from Japan to China in a time when sailors did not have the compass. On his own trip it took three attempts to finally arrive at port and when he did the embassy was forced to await the slow wheels of Chinese bureaucracy in a region recently hit by a locust-plague-induced famine. 

The Spread of Buddhism

The diary contains descriptions of local lore, Chinese inns, life in the monasteries, festivals, and the sights he encountered such as this lion statue which he reports took seven attempts and a good few prayers by the sculptor to complete: "It seems to be walking, and vapors come from its mouth. We looked at it for quite a while, and it looked just as if it were moving" (Keene, 360).

Return to Japan & Royal Approval

Prior to his return to Japan from China in 847 CE, Ennin famously employed a Shinto diviner and prayed to the Shinto gods Sumiyoshi (protector of sea voyagers) and the Dragon King of the Sea. This was a symbolic instance of the increasing complimentary nature of the Buddhist and Shinto faiths in ancient Japan. The effort was worth it as Ennin did make it back to Japan after another perilous sea trip. With him were 584 Buddhist texts, 21 ritual implements, and several paintings and mandalas for teaching purposes. Previously, Shingon Buddhism had been at the forefront of esoteric teachings in Japan, but now Ennin was armed with material and knowledge to champion the cause of the Tendai sect. 

Back at Enryakuji, the imperial court recognised Ennin’s superior Mikkyo knowledge and officially sponsored an annual esoteric initiation rite there (Hiei kanjo), starting in 849 CE. From the emperor’s point of view these rites, which involved over 1,000 monks, would ensure the security and well-being of the Japanese state. Ennin became a regular guest at the royal palace at Heiankyo and personally instructed imperial family members in the basics of Buddhism and lower initiation rites, including Emperor Montoku himself in 856 CE.      

Abbot of Enryakuji

In 854 CE Ennin became the Chief Abbot (Tendei Zasu) of the Enryakuji monastery, a position he held for over 20 years. The monastery was one of the most important in Japan, and Ennin enjoyed the continued political and financial support of both the imperial court and the powerful Fujiwara clan. A notable achievement during his leadership was the foundation of the Onjoji (aka Miidera) monastery on the lower slopes of the mountain. Other temples credited to Ennin include the Sanbutsudo Hall at Nikko Toshogu on the orders of Emperor Ninmyo (r.  833-850 CE) and on the island of Chikubushima where Ennin set up a statue of Benzaiten (Saraswati) in 834 CE following a dream in which the goddess asked to be enshrined there. 

Bell Tower, Enryakuji

Like many other scholar-monks of the period, Ennin was credited with being a gifted sculptor. One example of his work is the wooden copy of the Kannon Bosatsu statue at Asakusa Jinja in Tokyo. The original bronze figure was said to have been caught by fishermen and is a hihutsu or 'hidden image' which may not be revealed to human eyes. Even Ennin’s wooden copy is only put on display for one day each year (13th December).  

In the politics of the Heian Period (794-1185 CE) the power of monasteries, based on their landholdings, exemption from taxes, and ability to maintain significant armies of armed retainers, meant that inevitably rivalries broke out between them. Enryakuji endured a particularly bitter rivalry with the Kofukuji monastery at Nara. Enryakuji, though, would also split from within when the followers of Ennin and those of Enchin, abbot of Onjoji, decided to go their own way and form the Mountain Order and Jimon Order respectively. There does not seem to have been any significant doctrinal differences between the two groups except a reluctance to emphasise the mystic elements of Buddhism that Ennin preached. The split, which became official following Enchin’s death in 891 CE, may also have had more earthly reasons and been due to competition for resources and influence.    

Two years after his death in 864 CE, Ennin was given the posthumous title of Jikaku Daishi by the emperor, meaning 'Great Teacher of Compassionate Awareness', in recognition of his contribution to Buddhism and establishing the Tendai Mikkyo sect as the most important officially sanctioned sect in Japan. Tendai Buddhism continued to prosper over the following century with successive emperors favouring the sect and many of the monks ordained at Enryakuji would go on to administer secondary temple site across Japan.
