Heukseoksa is a temple founded no later than the Unified Silla Period and has the rock-cut Buddhist image of the Three Kingdoms Period and the Seated Stone Buddha (Treasure No. 681) of the Unified Silla Period. The temple had been destroyed by fire during the Japanese Invasion in 1592 and was rebuilt in 1945. It was not until 1990s that many relics were found from within the Wooden Amitabha Buddha enshrined in Daeungjeon Hall or the main building. The documents found with the relics revealed that the Wooden Amitabha Buddha was made in 1458 during the reign of King Sejo of Joseon as the Principal Buddha of the Buddha Triad of Beopcheonsa Temple. Consistent with this record is the style shown in the topknot and the clothes folds near the arms and stomach, which is typical in the earlier Joseon Dynasty. The location of the Beopcheonsa Temple, however, is unclear because many temples existed there with the same name in many regions including Gyeonggi-do, Gyeongsang-do and Jeolla-do. The relics in all are fourteen pieces of seven kinds including some Buddhist amulets, Bulsangjoseonggwongomun recording the list of donors and information of this Buddha image and Buljosamgyeonghapbu, a compilation of sutras. The contents found within the body are in accordance with the record of Josanggyeong, which was published by Yujeomsa Temple in 1824: Thirty-eight kinds of fabrics, five kinds of perfumery, five cereals and the Seven Treasures such as glass, pearl, amber, etc. These relics, revealing the production date of the Wooden Amitabha Buddha, are precious themselves especially for textiles and bibliographical research.
