He was a frustrated government official who, after a period of service, lost his position and devoted himself to sharing his thoughts on governance, ethics, and ritual. He attracted followers who were drawn to his wisdom and his vision of a better society. These followers learned from him through:
* Direct Discourses: He engaged in discussions and debates with his disciples, answering their questions and sharing his insights. The *Analects*, the primary source of Confucian teachings, is largely a compilation of these conversations and sayings.
* Observation and Imitation: Confucius emphasized the importance of modeling virtuous behavior. His disciples learned by observing his actions and attempting to emulate his conduct.
* Practical Application: Confucius's teachings weren't solely abstract; they focused on practical applications in daily life and governance. His disciples learned by applying his principles in various situations.
* A Wandering Scholar: Confucius and his followers traveled extensively, seeking patrons and sharing their knowledge. This period solidified his role as a teacher by bringing his ideas to a wider audience.
Essentially, Confucius became a teacher through a combination of personal charisma, intellectual depth, and the willingness of others to learn from him. His success was based on the influence he exerted and the dedication of his followers who diligently recorded and passed on his teachings. He didn't "become" a teacher in a single event; it was a gradual process that defined the remainder of his life.
