Acharya Prashant explains that fear is an inherent part of the human condition and the physical body. He asserts that fear will always exist as a possibility or a seed within the mind, and one should not seek its total destruction or ask how to be completely free from it. Just as a clean temple may have a dirty corner, the human existence will always have the presence of fear. The speaker emphasizes that while fear has its own domain, an individual has the choice of where to focus their attention. If one chooses to focus on the base and dirty aspects of life, they will continue to live in fear, guilt, and condemnation.
