Acharya Prashant explains that all forms of mental insecurity, such as the fear of losing money, marks, or prestige, are ultimately rooted in physical survival and the domain of the body. He distinguishes between the body and consciousness, asserting that fear belongs to the biological domain of the body. The fundamental problem arises when one identifies with the body, a state known as 'Ahamdehasmi'. He advises that instead of fighting fear, which requires entering the body's domain and thus succumbing to it, one should simply ignore it and focus on the tasks suggested by consciousness. Using the example of protecting a loved one from a wild beast, he illustrates that consciousness and responsibility can override biological fear.
