Manpasikjeok: The Flute That Calms Ten Thousand Waves

King Munmu of Silla (r. 661-681) completed the unification of most of the Korean peninsula under Silla. The *Samguk Sagi* records his deathbed instructions: he was to be cremated in the Buddhist manner and his remains buried in the East Sea. The *Samguk Yusa* adds that he wished to become a great dragon after death, to protect the kingdom from invaders and uphold the Buddhist law. His son, King Sinmun, completed the temple of Gameunsa on the coast, 'the temple of gratitude', in his father's honor.

In the fifth month of 682, the *Samguk Yusa* says, an official reported that a small mountain was floating toward Gameunsa on the East Sea, drifting back and forth with the waves. The king's diviner said that the late king, now a sea dragon, and the great general Kim Yu-sin, now a god in heaven, wished to send a treasure to guard the state, and that the king should go to the shore. The mountain was shaped like the head of a turtle, and on its top grew a bamboo that was two stalks by day and joined into one by night.

The king went to the pavilion called Iyeondae to watch. When the bamboo became one, heaven and earth shook, and a storm and darkness lasted seven days. When they cleared, the king sailed to the mountain, and a dragon came to him bearing a belt of black jade. The king asked why the bamboo parted and joined. The dragon answered: just as one hand cannot make a sound but two hands clapping can, this bamboo makes sound only when joined. It is a sign that the king will rule the world by sound. Cut it and make a flute, and the whole world will be at peace. Your father has become a great dragon of the sea, and Kim Yu-sin a god of heaven; the two sages of one mind have sent this treasure.

The king had the bamboo cut, and the mountain and the dragon vanished. He made a flute from it and kept it in the royal treasury. When it was played, enemy armies withdrew, sickness was healed, drought brought rain and floods cleared, and the wind died and the waves grew calm. It was called Manpasikjeok, 'the flute that calms ten thousand waves', and honored as a national treasure. Later kings, the *Samguk Yusa* says, gave it further titles when it was lost and found again.

Off the coast near Gameunsa stands Daewangam, 'the rock of the great king', traditionally identified as King Munmu's underwater tomb, and the ruins of Gameunsa still show its twin stone pagodas. The story joins the Silla state's Buddhist piety with older ideas of sea dragons as guardians.
