Acharya Prashant explains that a real teacher has a great responsibility to make himself unnecessary. He questions the validity of a teacher who is known by his followership, noting that the real ones hardly ever had any. The primary duty of the teacher is to make himself redundant. You have truly helped someone only if they no longer need your help. However, if a Guru has his own self-interest in mind, he will ensure that you return to him day after day. You will continue to return to him only if he pleases you, which is a clear indication of the Guru's self-interest. The speaker states that the real teachers were always myth-busters and iconoclasts. They never pleased their audiences, which is why they were often discarded, ostracized, stoned, killed, or crucified. They had no concern for the status quo or for what people liked. They were not pleasant, smiling, or interested in making people feel good. They were not bothered whether you returned to them and did not make arrangements for large crowds to gather. The rightful role of the teacher is to show that a teacher is not needed and that you are self-sufficient. The speaker gives examples from Zen, where masters would carry a stick and hit their disciples hard to wake them up. He recounts a story of a Zen master who cut off a disciple's finger, leading to the disciple's immediate enlightenment. The real teacher would never be too acceptable or appear as a pleasing, fatherly figure. Acharya Prashant clarifies that only that which allows you to continue as you are, as an extension of your ego, is pleasing. The teacher's responsibility is to not let you continue as you are. If you really like a teacher, it proves he is like a plum cake for you, pleasing your senses. This liking comes from the same center as liking a shopping mall. The real teacher, in contrast, would not be a pleasing personality; prominent teachers in India have often been depicted carrying weapons, not as gentle figures.
