By the time of his reign, Buddhism had become fairly common in Silla, as it had been introduced much earlier by Goguryeo monks during King Nulji's reign. One of King Beopheung's ministers, a man named Ichadon, was a Buddhist convert who had even shaved his head and took the tonsure. He constantly implored the king to adopt Buddhism as the state religion, and in fact King Beopheung himself had become fond of Buddha's teachings. However, the other ministers of Silla were greatly opposed to this, and expressed such defiance to the king. Beopheung, having been persuaded by his ministers, was at a crossroads, and encountered great reluctance to change. At this time, Ichadon suggested his own martyrdom and pleaded with the king to execute him in public for the cause of Buddhism. This the king refused to do, and so Ichadon deliberately insulted the ministers of the kingdom, thus provoking the anger of the king. In the end, Ichadon was executed in public, but before his head was cut off, he stated that the blood spilled from his body would not be red but milky white. According to the Samguk Yusa, his predictions proved correct, and Ichadon's milky blood horrified the ministers of the kingdom. As a result of Ichadon's matyrdom, King Beopheung finally chose Buddhism as the state religion. However, true Buddhist freedom in Shilla would not begin until the reign of King Jinheung.
