Acharya Prashant explains that while beliefs may change over time, the underlying tendency to believe and the reliance on thought often remain unchanged. He compares this to a body with low immunity where diseases come and go, but the fundamental weakness persists. He points out that people often change inconsequential things, like political affiliations or personal belongings, as a conspiracy to avoid changing the core self. The thinker, the chooser, and the reliance on memory are the elements that truly need transformation, yet individuals cling to the right to choose even when they are willing to alter their choices.
