Acharya Prashant explains that every individual possesses their own inner light and understanding. When one operates from this inherent clarity, there is no room for doubt or the need for excessive deliberation; actions flow naturally and confidently. However, the human mind often ignores this inner light, preferring to rely on borrowed instructions and external benchmarks. This reliance on external standards creates a tragic situation where capable individuals feel the need for constant validation, leading to a life filled with fear and hesitation. The speaker emphasizes that fear arises because we are constantly trying to measure ourselves against standards given by others, which can never truly belong to us.
