Acharya Prashant addresses the misconception that fear is a necessary or desirable trait simply because it is an evolutionary tool provided by nature. He explains that a human being is not a single entity but consists of two parts: the body and consciousness. While fear is a mechanism embedded by nature to ensure the physical survival of the body, it is essentially animalistic. Animals are primarily driven by bodily needs such as security, food, and reproduction, but humans are defined by their consciousness, which is of higher importance than the body.
