Acharya Prashant explains that while external growth is typically measured by accumulation, power, and status, it must be evaluated based on its contribution to the welfare of the self. He defines inner growth as the process of identifying and reducing the primordial tendencies one is born with, such as fear, greed, and ignorance, which are often exacerbated by social conditioning. He clarifies that inner growth is not about adding more to oneself but is rather a process of simplification and reduction, likening it to the shrinking of an internal tumor. Every external endeavor should be measured by its utility in facilitating this internal cleansing and well-being.
