A story about the origin of the Correcting Mistakes Mantra, 補闕眞言

Then Jijang Bosal told Linju that instead of leading Linju on to his next life, he was going to teach Linju a mantra and then send him back to his previous life so he could teach the mantra to Daoru and everyone else. Everyone should chant this mantra in order to correct the mistakes we make in our chanting. After being “dead” for seven days, Linju suddenly recovered and told everyone about his encounter with Jijang Bosal, and the mantra he had been taught.
