The Vairocana Buddha, which was believed to be the commander of spreading truth thoroughly around the world, was originally located in Donggye-ri, Seobang-myeon, Gwangju, and subsequently moved to Jeungsimsa Temple in 1934. Although the mandorla (Buddhist halo of light) and the pedestal are missing, the statue itself is complete. The usnisa (protuberance on top of Buddha's head), which is shaped like a topknot on top of the wavy hair, is placed up high and shown clearly. The oval smiling face harmonized with the eyes, nose, mouth, and other features show a realistic expression of the human figure. The Beobui (sacerdotal robes) covering the shoulders as well as the wide chest is very thick that the curves of the body are hidden, but its well-proportioned sizes down to the knees give a sense of stability. The thick lower ends of the clothes covering two arms run down, making the regular folds parallel. The hand position is uniquely expressed such that the left hand holds the right index finger and is in contrast to the general style of Vairocana Buddha. Although this iron seated statue does not show outstanding carving methods, the balance of the statue is remarkable. Along with the Iron Seated Vairocana Buddha of Dopiansa Temple in Cheorwon (National Treasure No. 63) and the Iron Seated Vairocana Buddha of Borimsa Temple in Jangheung (National Treasure No. 117), this iron seated Vairocana Buddha is assumed to have been built at the end of the Silla Dynasty in the 9th century.
