Acharya Prashant explains that living a righteous life is essentially an act of rebellion against nature and social structures, which often results in internal and external resistance. He emphasizes that when one decides to change their life, their own body and emotions may initially revolt through laziness, physical pain, or irrational feelings. This is a natural mechanism of the subconscious mind trying to pull the individual back into their old, comfortable patterns. He advises that one must endure this phase with a firm resolve, as the body and mind eventually settle down once they realize the individual will not yield to their tactics.
