Acharya Prashant explains that while certain bodily functions are involuntary and operate without our consent, humans tend to suppress and interfere with aspects of themselves where voluntary response is possible. He notes that it is a relief that vital functions like the heartbeat, fatigue, and hunger are involuntary, as human morality and norms of right and wrong would otherwise restrict them. He argues that man is the only creature that imposes artificial norms upon the body, often attempting to mess with natural systems in the name of improvement or due to shame. This restrictive behavior towards oneself is the root of man's cruelty and lack of unconditional acceptance toward the rest of the world. The speaker highlights that mankind shares a common feeling of imperfection and incompleteness, which becomes the primary driver for most actions. People are constantly driven by the urge to better themselves through external means, such as seeking better jobs, bigger houses, or social respect. Acharya Prashant questions the origin of these standards for betterment, pointing out that they are not innate but are implanted by society. He suggests that our sense of self-worth is often based on foreign criteria and the respect others accord to us, leading to a life spent chasing external validation rather than being driven by a feeling of already being alright.
