Dainichi Nyorai (Enjō-ji)

The seated wooden statue of Dainichi Nyorai (木造大日如来坐像, mokuzō Dainichi Nyorai zazō^?) at the Shingon temple of Enjō-ji in Nara is the earliest and best-substantiated work by Japanese master sculptor Unkei. An inscription on the pedestal records that he began work on the piece in 1175 and brought it to completion the following year. The sculpture has been designated a National Treasure. Unkei's next documented works, from the early 1180s, were commissioned by military leaders prominent in the ensuing Kamakura shogunate, for temples in eastern Japan. These works are physically more massive and powerful, as are his giant Niō at Tōdai-ji. By contrast, in this early work Unkei employed a more "gentle" or "tranquil" style.

Dainichi Nyorai (Sanskrit: Mahāvairocana) is the central deity of Esoteric Buddhism. As opposed to the "revealed teaching", understandable to the intellect of the common man, the "concealed teaching" (mikkyō) of Esoteric Buddhism offers Buddhahood and paradise on earth to the initiate, through ritual practice and the contemplation of sacred images. According to Kūkai, the founder of the Shingon school of Esoteric Buddhism in the early ninth century, "because the secret storehouse [Mikkyō teaching] is so profound and mysterious it is difficult to manifest with brush and ink [text]. Thus it is revealed to the unenlightened by adopting the form of images. The great variety of postures and mudrās are the effect of Buddha's great compassion. With a single glance [at the images] one becomes a Buddha."
