Acharya Prashant explains that the primary obstacle to spirituality is not a complex mental issue but a basic, material concern for physical survival. He asserts that the 'old' self is deeply rooted in the body's need for food and security, making it difficult for an individual to leave their current state. The mind often creates rationalizations and intellectual excuses to hide the fact that it is actually the body's fear of hunger and lack of shelter that prevents spiritual progress. He describes the final spiritual battle as a 'street fight' rather than a peaceful, isolated experience, requiring physical strength and the ability to endure real hardship. He points out that in India, the historical memory of famines makes the fear of hunger particularly potent, leading people to remain in miserable situations out of a fear for their physical sustenance. Acharya Prashant emphasizes that a saint must be prepared to face physical violence and wounds, rather than just romanticized peacefulness. He highlights that traditional yogic practices, such as fasting and physical discipline, were designed to conquer the body's dominance. Ultimately, he suggests that one who can transcend the fear of physical elimination and the need for comfort cannot be enslaved by the world.
