Acharya Prashant explains that the inability to say 'no' and the constant concern for one's social image are rooted in greed and body-identification. He asserts that the desire to maintain a positive impression in the minds of others is not natural or sensitive, but a calculated move for material gain. People protect their reputation because they believe it will help them acquire resources, security, or physical comforts from others. This behavior is fundamentally driven by the 'body-sense' (Deh-bhav), where one identifies so strongly with the physical self that they become dependent on external validation to secure material needs.
