King Ajātaśatru stood against Śākyamuni Buddha, but on the urging of Minister Jivaka he put faith in the Lotus Sūtra and governed the whole country. King Wonderful Adornment was advised by his two princes and corrected his mistaken views. What happened in your situation is the same. I believe your advice softened the heart of your lord. This is solely due to your deep faith in the Lotus Sūtra.
