Acharya Prashant explains that sickness is inherently 'the other' and foreign to one's true nature. He clarifies that if someone else's sickness or behavior is bothering a person and making them restless, it indicates that they have contracted that sickness themselves. Just as a virus comes from outside but causes disease once it infects a host, the sickness of the world becomes one's own when it starts to influence the mind. He emphasizes that the first step in dealing with external sickness is to ensure one's own system remains healthy and free from infection, influence, or impact. To deal with the nonsense of the world, one must maintain a distance, which is the essence of witnessing and realization. He concludes that one cannot understand a condition like blindness by becoming blind; instead, one must maintain aloofness and purity before engaging with, studying, or fighting the sickness of the world.
