Although Zhenyan lost its position of prominence in China after the persecution of 845, it maintained spiritual vitality and communal visibility through the Song dynasty (960–1279). Moreover, the Zhenyan school contributed a great deal that has endured in the larger fabric of Chinese religion. Shingon
Although Vajrayana Buddhism played a much greater role in China than is usually recognized, it was in Japan that it became most influential. Esoteric elements, called taimitsu in Japanese, have been an important element in the Japanese Tendai school, which was founded by the monk Saichō (764–822), who studied with Zhenyan and Tiantai masters in China. The most systematized and elaborated expressions of the Vajrayana tradition, however, were developed in the Shingon school, the Japanese version of Zhenyan.

The founder of the Shingon school in Japan was Kūkai, better known by his posthumous name, Kōbō Daishi (Japanese: “Great Master Who Understood the Dharma”). An exceptional scholar, poet, painter, and calligrapher, he wrote a treatise comparing Confucian, Daoist, and Buddhist thought and naming the latter as superior. Although trained for government service, he experienced a change of heart and became a Buddhist monk. Like many monks in pursuit of the pure Buddhist doctrine, he journeyed to China, where he met the master Huiguo, who recognized Kūkai’s potential and taught him Zhenyan Buddhism. After the death of Huiguo, Kūkai returned to Japan, where he received many governmental honours and established a monastery on Mount Kōya as the centre of Shingon Buddhism.
In propagating the teachings of his school, Kūkai wrote many important texts, including the Jūjū shinron (Japanese: “The Ten Stages of Consciousness”). In this work Kūkai presented a model of the development of the spiritual life that arranged Buddhist teachings and those of other religions into a hierarchical system. He taught that the first stage of human spiritual development was one in which humans are controlled by their instincts. In the second stage, which Kūkai identifies with Confucian teachings, human beings attempt to live a proper moral existence. The third stage, in which the individual strives for supernatural powers and heavenly rewards, is that of Brahmanism and Daoism. The fourth and fifth stages of spiritual development are taught by the Hinayana schools and are characterized by the striving for self-enlightenment. Stages six to nine, identified with the Mahayanist teachings of Hossō, Sanron, Tendai, and Kegon, lead the individual to compassion for others. The zenith of spiritual development is identified by Kūkai with the esoteric teachings of Shingon.
The Shingon school claimed that its doctrine was the purest because it was not based on the teachings of the historical Buddha, Shakyamuni, who expounded his doctrine with the limitations of his audience in mind, but on the timeless and immutable teachings of the Buddha in his dharmakaya, or cosmic body. This buddha, named Mahavairochana, was felt to be beyond all earthly dualism and impurity but at the same instant to be within all things as their buddha nature.
In Shingon the realization that one’s own buddha nature is identical with Mahavairochana is enlightenment. This enlightenment, as depicted in Kūkai’s treatise Sokushin-jōbutsugi (Japanese: “The Doctrine of Becoming a Buddha with One’s Body During One’s Earthly Existence”), can be achieved in this world while possessing a human body. To achieve this enlightened state, however, the aspirant must receive the secret doctrine of Shingon orally and directly from a Shingon master. The truth that the master reveals is founded on the ritual mysteries of the body, speech, and mind; these mysteries invoke cosmic forces embodied in the buddhas and bodhisattvas with which the aspirant identifies before becoming one with Mahavairochana. The experience of the mystery of the body involves the use of mudras: devotional gestures of the hands and fingers, postures of meditation, and the handling of such sacred instruments as the vajra (“thunderbolt” or “diamond”) and the lotus. The mystery of speech involves the recitation of dharanis or mantras, mystical verses and sounds believed to be the essence of the cosmic forces with which one wishes to commune. Attaining the mystery of the mind involves yogic contemplation of and absorption in the buddha Mahavairochana and his attendants.
The aspirant is further helped in his quest to identify his buddha nature with the Cosmic Buddha by means of two mandalas, often placed on the Shingon altar. The mandalas, believed to contain all the power of the cosmos, were drawn in accordance with the teaching of Huiguo, who maintained that the buddha Mahavairochana’s doctrines were so profound that their meanings could be conveyed only in art. One mandala, called the “Diamond Mandala” (based on the Tattvasamgraha and known in Japanese as kongō-kai), portrays the buddha Mahavairochana sitting upon a white lotus in deep contemplation, surrounded by the buddhas of the four regions. This symbolizes Mahavairochana’s indestructible, immutable, or potential aspect. The second mandala, called the “Womb Mandala of Great Compassion” (based on the Mahavairochana-sutra and known in Japanese as taizō-kai), reveals Mahavairochana sitting on a red lotus surrounded by innumerable buddhas, bodhisattvas, and Indian gods, with consorts. This represents the Cosmic Buddha’s dynamic manifestation in which he is immanent in everything. It was believed that, by meditating correctly on these two mandalas, the aspirant would realize the unity beyond the diversity of the world.
The emphasis of Shingon upon ritual, symbolism, and iconography, coupled with the government’s praise of Kūkai and the bestowal upon him of the shrine for the protection of the country, made Shingon very popular in Japan. Shingon’s popularity was a cause of the growth of Ryōbu Shintō (Japanese: “Two Aspects Shintō”), which identified Shintō kami" class="md-crosslink">kami (object of worship or sacred power) with bodhisattvas. Moreover, believing that Shingon rites controlled the forces of the cosmos, many people used them to ward off evil and bring supernatural help in everyday life. While this combination of esoteric Buddhism with more this-worldly concerns caused schisms, Shingon maintains its position as one of Japan’s strongest Buddhist schools. Mythology
Myth in Buddhism is used at various intellectual levels in order to give symbolic and sometimes quasi-historical expression to religious teachings. Accepted on its own terms, Buddhism is a supernatural religion in the sense that, without a buddha to reveal them, the truths remain unknown. Only after human beings have received the Buddha’s revelation can they proceed apparently by their own efforts. This teaching was explicit in the early schools, in which the revelation was still thought of as historically related to Shakyamuni’s mission in the world. Gradually some Buddhists developed the idea of the Buddha’s continuous revelation and gracious assistance, deriving from his glorified state of time-transcending enlightenment. Thus, the comparatively simple mythology of the great Buddha myth developed into the far more elaborate tradition of Mahayana.
