Acharya Prashant explains that the human mind is often occupied by the 'devil,' which manifests through popular idioms, folk tales, and cultural beliefs that lack any scriptural basis. He points out that people hold deep faith in ideas that were never taught by prophets or scriptures, yet they believe these notions are spiritual. He highlights how individuals even misattribute their own mundane thoughts to great figures like Swami Vivekananda to gain credibility, leading to a distortion of the original teachings. He asserts that most of what people consider sacred or central to life has never been spoken by any wise source, avatar, or prophet, and challenges listeners to verify their social beliefs against actual scriptures, predicting that less than ten percent would find any support.
