Shingon Buddhism (眞言, 真言 "
true words") is a major school of
Japanese Buddhism, and is the other extant major branch of
Vajrayana Buddhism along with
Tibetan Buddhism. It is often called "Japanese Esoteric Buddhism". The word
shingon is the
Japanese reading of the
kanji for the Chinese word
zhēnyán, literally meaning "true words", which in turn is the Chinese translation of the
Sanskrit word
mantra.
History
Shingon Buddhism arose in
Japan's
Heian period (794-1185) when the monk
Kūkai went to
China in 804 and studied
tantric practices in the city of
Xian and returned with many texts and art works. In time, he developed his own synthesis of esoteric practice and doctrine, centered on the universal
Buddha Vairocana (or, more accurately, Mahavairocana Tathagata). He established a monastery on
Mount Koya, which became the head of the Shingon sect of Buddhism.
Shingon enjoyed immense popularity during the
Heian Period, particularly among the Heian nobility, and contributed greatly to the art and literature of the time, as well as influencing other communities, such as the
Tendai sect on
Mt. Hiei.
Also, Shingon's emphasis on ritual found support in the
Kyoto nobility, particularly the
Fujiwara clan. This favor allotted Shingon several politically powerful temples in the capital, where rituals for the imperial family and nation were regularly performed. Many of these temples such as
Toji and
Daigoji in the South of Kyoto and Jingoji and
Ninnaji in the Northwest became ritual centers establishing their own particular ritual lineages.
Schism
Like the Tendai School that branched into the
Jōdo,
Zen and
Nichiren Schools in the
Kamakura period, Shingon also divided into two major branches: and . This division primarily arose out of a political dispute between
Kakuban and his faction of priests centered at the
Denbō-in Hall (伝法院) and the leadership at
Kongōbuji, the head of
Mt. Kōya. Kakuban, who was originally ordained at
Ninnaji in Kyoto, studied at several temple-centers (including the Tendai temple complex at Onjiyōji) before going to Mt. Kōya. Through his connections, he managed to gain the favor of high ranking nobles in Kyoto, which helped him to be appointed abbot of Mt. Kōya. The leadership at Kongōbuji, however, opposed the appointment on the premise that Kakuban had not originally been ordained on Mt. Kōya. After several conflicts Kakuban and his faction of priests left the mountain for Mt. Negoro to the northwest, where they constructed a new temple complex, now known as
Negoroji. After the death of Kakuban in 1143, the Negoro faction returned to Mt. Kōya. However in 1288, the conflict between Kongōbuji and the Denbōe came to a head once again. Led by
Raiyu, the Denbōe priests once again left Mt. Kōya, this time establishing their headquarters on Mt. Negoro. This exodus marked the beginning of the Shingi Shingon School at Mt. Negoro, which was the center of Shingi Shingon until sacked by
Hideyoshi Toyotomi in 1585.
During the initial stages of his predication in Japan, the Catholic missionary
Francis Xavier was welcomed by the Shingon monks since he used the word
Dainichi for the
Christian God. As Xavier learned more about the religious nuances of the word, he changed to
Deusu from the Latin and Portuguese
Deus. The monks also realized by that point that Xavier was preaching a rival religion.
Teachings
The teachings of Shingon are based on esoteric
Vajrayana texts, the
Mahavairocana Sutra and the
Vajrasekhara Sutra (Diamond Crown Sutra) and the
Shurangama Sutra with its
Shurangama Mantra based around
Vairochana and
Akshobhya and
Sitatapatra. These two mystical teachings are shown in the main two
mandalas of Shingon, namely, the
Womb Realm (Taizokai) mandala and the
Diamond Realm (Kongo Kai) mandala. Vajrayana Buddhism is concerned with the ritual and meditative practices leading to
enlightenment. According to Shingon, enlightenment is not a distant, foreign reality that can take
aeons to approach but a real possibility within this very life, based on the spiritual potential of every living being, known generally as
Buddha-nature. If cultivated, this luminous nature manifests as innate wisdom. With the help of a genuine teacher and through properly training the body, speech, and mind, we can reclaim and liberate this enlightened capacity for the benefit of ourselves and others.
Kūkai also systematized and categorised the teachings he inherited into ten stages or
levels of spiritual realisation. He wrote at length on the difference between
exoteric (both mainstream Buddhism and
Mahayana) and
esoteric (
Vajrayana) Buddhism. The differences between exoteric and esoteric can be summarised as:
- Exoteric Buddhism holds that the ultimate state of Buddhahood is ineffable, and that nothing can be said of it. Esoteric Buddhism holds that while nothing can be said of it verbally, it is readily communicated via esoteric rituals which involve the use of mantras, mudras, and mandalas.
- Kūkai held that exoteric doctrines were merely provisional, skillful means (upaya) on the part of the Buddhas to help beings according to their capacity to understand the Truth. The esoteric doctrines by comparison are the Truth itself, and are a direct communication of the "inner experience of the Dharmakaya's enlightenment".
- Some exoteric schools in late Nara and early Heian Japan held (or were portrayed by Shingon adherents as holding) that attaining Buddhahood is possible but requires a huge amount of time (three incalculable aeons) of practice to achieve, whereas esoteric Buddhism teaches that Buddhahood can be attained in this lifetime by anyone.
Kūkai held, along with the
Huayan (Jp.
Kegon) school that all phenomena could be expressed as 'letters' in a '
World-
text'. Mantra, mudra, and mandala are special because they constitute the 'language' through which the Dharmakaya (i.e. Reality itself) communicates. Although portrayed through the use of anthropomorphic metaphors, Shingon does not see the
Dharmakaya Buddha as a
god, or creator. The Dharmakaya is in fact a symbol for the true nature of things which is impermanent and empty of any essence. The teachings were passed from
Mahavairocana.
Mahavairocana Tathagata
thumb|Thirteen Buddhas of Shingon Buddhism./" class="wiki">Samantabhadra is one of the
Thirteen Buddhas of Shingon Buddhism.
In Shingon,
Mahavairocana Tathagata is the universal or
primordial Buddha that is the basis of all phenomena, present in each and all of them, and not existing independently or externally to them. The goal of Shingon is the realization that one's nature is identical with Mahavairocana, a goal that is achieved through
initiation (for ordained followers),
meditation and esoteric ritual practices. This realization depends on receiving the secret doctrine of Shingon, transmitted orally to initiates by the school's masters. Body, speech, and mind participate simultaneously in the subsequent process of revealing one's nature: the body through devotional gestures (
mudra) and the use of ritual instruments, speech through sacred formulas (
mantra), and mind through
meditation.
Shingon places special emphasis on the
Thirteen Buddhas, a grouping of various Buddhas and boddhisattvas:
Mahavairocana is the Universal Principle which underlies all Buddhist teachings, according to Shingon Buddhism, so other Buddhist figures can be thought of as manifestations with certain roles and attributes. Each Buddhist figure is symbolized by its own Sanskrit "seed" letter as well.
Practices and features

A typical Shingon shrine, with Mahavairocana at the center of the shrine, and the Womb Realm (Taizokai) and Diamond Realm (Kongokai) mandalas.
One feature that Shingon shares in common with the other surviving school of Esoteric Buddhism (Tendai) is the use of
seed-syllables or
bija (
bīja) along with anthropomorphic and symbolic representations, to express Buddhist deities in their
mandalas. There are four types of mandalas:
mahā-maṇḍala (大曼荼羅, anthropomorphic representation), the seed-syllable mandala or
dharma-maṇḍala (法曼荼羅), the
samaya-maṇḍala (三昧耶曼荼羅, representations of the vows of the deities in the form of articles they hold or their mudras), and the
karma-maṇḍala (羯磨曼荼羅 ) representing the activities of the deities in the three-dimensional form of statues, etc. An ancient
Indian Sanskrit syllabary script known as
siddham (Jap.
shittan 悉曇 or
bonji 梵字) is used to write mantras. A core meditative practice of Shingon is
ajikan (阿字觀), "Meditating on the Letter 'A'", which uses the
siddham letter representing that sound as a. Other Shingon meditations are
Gachirinkan (月輪觀, "full moon" visualization),
Gojigonjingan (五字嚴身觀, "visualization of the five elements arrayed in the body" from the
Mahāvairocanābhisaṃbodhi-sūtra) and
Gosōjōjingan (五相成身觀,
pañcābhisaṃbodhi "series of five meditations to attain Buddhahood" from the
Sarvatathāgatatattvasaṃgraha).
The essence of Shingon Mantrayana practice is to experience Reality by emulating the inner realization of the Dharmakaya through the
meditative ritual use of mantra, mudra and visualization of mandala (ie. the three mysteries). All Shingon followers gradually develop a teacher-student relationship, whereby a teacher learns the disposition of the student and teaches practices accordingly. For lay practitioners, there is no initiation ceremony beyond the
Kechien Kanjō (結縁灌頂), which is normally offered only at
Mt. Koya but can also be offered by larger temples under masters permitted to transmit the empowerment. It is not required for all laypersons to take.
In the case of disciples wishing to ordain as priests, the process is more complex and requires initiations in various mandalas, rituals and so on. In either case, the stress is on finding a qualified and willing mentor who will guide you through Shingon practice at a gradual pace.
Esoteric Buddhism is also practiced, in the Japanese
Tendai School founded at around the same time as the Shingon School in the early 9th century (
Heian period). The term used there is
Mikkyo.
