【正确答案】 1、正确答案：In ancient times those who wanted to learn would seek out a teacher, one who could propagate the doctrine, impart professional knowledge, and resolve doubts. Since no one is born omniscient, who can claim to have no doubts? If one has doubts and is not willing to learn from a teacher, his doubts will never be resolved. Anyone who was born before me and learned the doctrine before me is my teacher. Anyone who was born after me but learned the doctrine before me is also my teacher. Since what I desire to learn is the doctrine, why should I care whether he was born before or after me? Therefore, it does not matter whether a person is high or low in position, young or old in age. Where there is the doctrine, there is my teacher.
