Answer:
Dear and respected Prince Shotoku, I refer to you in the humblest way a servant of yours can have to explain to you why your piety and your wisdom can help us accomplish your goals better. Please you all mighty sir, I beg you to consider my proposal to let us earn the right of working more for you and to accomplish your goals in a faster and more effective way by sharing the tasks. Also, to supervise the immediate officials, as some of them are corrupt and abuse from us, as they use their power to abuse from us, to threaten the balance of your realm, and by conspiring against its functionality.
Step-by-step explanation:
The reason behind this letter is because first of all the prince was a very authoritarian and superb individual. He believed he was fallen from the sky and that he was from god's lineage. Therefore, people had to speak to him as if they eared him, also this type of letter defying his ideas would end up most likely in seppuku because you couldn't tell him what to do. But by bringing the facts that the fundaments of our petition were to provide him a better job, that would be heard. Also, by declaring that some of his officials were corrupt and threatened the stability of the realm, as well as letting him know they endangered his position.
