Acharya Prashant addresses a question about the meaning of filling one's life with the highest possible work. He explains that this is not a constructive process of adding something, but rather a process of emptying or draining out what is low. He clarifies that his statement to "fill yourself up with the highest" should be interpreted in a negative way, meaning one must "drain out the lowest." We inherently know what is not high in our lives, and the task is to empty our lives of these things. He elaborates by asking the audience to identify what is low in their lives, with examples like gluttony, instant gratification, pleasure, and fear being mentioned. Focusing on fear, he describes it as something that energizes him, presenting an opportunity for a duel. He admits he doesn't always win but emphasizes the importance of putting up a good fight. This struggle against the low is a duty everyone is capable of. The highest work is to fight whatever does not add dignity to life, to have some "steel within," and not to surrender easily to things like fear. This refusal to surrender to the lowly is what he defines as spirituality and real surrender. It is not about bowing to an imaginary God but about not surrendering to fear and temptation. He connects this principle to Vedanta, which he calls a "loud, thundering no," and its method of "Neti Neti" (not this, not this). The mark of a truly young and alive person is to meet life with this powerful "No." By saying "no" to the usual, superficial aspects of life, one is implicitly saying a resounding "yes" to a real life. He advises that since most things in life are temptations that do not add dignity, one's stock reply should be "No." This constant refusal to accept the superficial is the path to embracing what is real and constitutes the highest work.
