Acharya Prashant discusses the nature of violence, sensitivity, and the true meaning of gratefulness. He explains that violence is not merely gross physical acts like beating a child but exists in increasingly subtle forms, such as shaming, ignoring, or even imposing one's beliefs through thought. He emphasizes that a sage is someone with the extreme sensitivity to perceive these subtle layers of violence that most people ignore. The speaker argues that the mind itself, in its basic functioning of creating distinctions and models, is often a source of violence.
