An arrogant king heard that Stongsem Mnyasca was very good at deceiving people, thinking that Stongsen Mnyasca couldn't deceive him. The king forced Stongsem Mnyasca to lie to him once, threatening to kill him if he didn't lie to him. Stongsem Mnyasca replied that his deceptions stemmed from a book, and that he had to go home to retrieve this book. So Stongsem mnyasca left the king's palace and came to another mountain, and he cried out to the king, threatening to steal his conch within fifteen days. However, on the night of the sixteenth day, when the guards were exhausted and fell asleep, Stongsem mnyasca entered the palace and stole the conch.
