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 the feeling of disability does not arise from the physical condition itself but from an imaginary comparison with an ideal state or one's past health. He uses a thought experiment regarding brain size and IQ to illustrate that we only feel disabled when we nurture a model of 'normalcy' that is different from our current reality. He emphasizes that if one accepts their current state as normal and recognizes that there is no alternative, the psychological suffering and the sense of being disabled will vanish.
