Acharya Prashant addresses a PhD scholar suffering from coccydynia, a condition causing chronic tailbone pain that limits his ability to sit and work. The speaker explains that mental stress and the feeling of disability do not arise from the physical condition itself but from an imaginary comparison with an ideal or a past healthy state. He uses a thought experiment to illustrate that if we compared our ordinary brains or bodies to a superior ideal, we would all consider ourselves disabled. Therefore, the solution lies in accepting one's current state as normal and removing the alternative from one's mind. By eliminating comparison, one eliminates the suffering associated with the condition.
