How does emerson define greatness in self reliance

"‘Ah, so you shall be sure to be misunderstood.’ — Is it so bad, then, to be misunderstood? Pythagoras was misunderstood, and Socrates, and Jesus, and Luther, and Copernicus, and Galileo, and Newton, and every pure and wise spirit that ever took flesh. To be great is to be misunderstood.”

Explanation:

This line implies that, usually, the general population does not accept or understand greatness. As long as a person lives with his dreams and passions, whether accepted or not, it is right for his well-being. Another interpretation of this phrase can be that someone sees a completely different perspective of ideas and things in such a way that no one has ever thought or seen them before, because of their outlook about things and ideas is unusual.
