Acharya Prashant explains that one must withdraw time and energy from things that do not provide peace and instead invest them in knowledge, love, and meaningful work. He emphasizes that sadness and emptiness only enter a mind that is vacant; therefore, one should fill every moment with high-quality actions and spiritual practice. He notes that human beings are born with innate tendencies like anger, fear, and greed, which are the root causes of suffering. To overcome these, sincere internal effort and spiritual discipline are required rather than external physical labor.
