Acharya Prashant explains that the more sensitive a person is to their worldly and biological suffering, the easier it will be for them to identify the right teacher. Being sensitive to one's existing suffering makes one more sensitive to the prospect of freedom from it. He uses an analogy: if you have very little pain, it is difficult to detect whether a pill is working. However, if you have intense pain, it becomes very easy to detect the efficacy of the pill; you will immediately know if it is virtuous or bogus. Applying this to the spiritual path, those who are genuinely feeling suffocated in the world do not make a mistake in choosing their teacher. Their pain is so intense that if a teacher's methods do not work, they will know immediately. They demand a real solution because they can no longer bear their intense pain. Conversely, those who are not in much pain in the world are the ones who get exploited. They might go to gurus as a matter of fashion, to add to their worldly trophies. Since they are not very dissatisfied with their current life, they have no real suffering to use as a litmus test and are thus susceptible to fraudulent teachers. Those with no real pain to begin with are the ones who get exploited by fake gurus. The speaker ironically notes that these fraudulent teachers, by exploiting people, give them real suffering, which in turn might lead them to a real teacher. He concludes by stating that the ego hates to hear that one cannot achieve liberation on their own. The belief that "I'll learn from life on my own" is a delusion taught by all great teachers. The more you try to do it on your own, the more you will get entangled in your own web.
