Acharya Prashant discusses the relationship between the mind's state and physical appearance, noting that while he cannot authoritatively comment on the biological existence of a 'medha' nerve, a mental transformation certainly changes one's face. He explains that thoughts of lust, greed, and violence radiate from a person, which even animals and infants can perceive. Conversely, a peaceful and silent mind allows one to read the movements and thoughts of others, as illustrated by a story of a student of Buddha who was overwhelmed by a female hermit's ability to perceive his inner desires. This stillness of mind is what creates a perceptible 'aura' around realized beings, though this extraordinariness is often met with indifference or hostility by the majority of people.
