Acharya Prashant defines business as a relationship where one's gain is dependent on another's loss, such as a seller profiting from a buyer's higher payment. In contrast, love is defined as a connection where both parties benefit simultaneously, proving that human beings are interconnected. He emphasizes that true happiness and peace are not about silence or inactivity but about not letting external disturbances overpower one's internal state. One can be active, argumentative, or even loud while remaining internally peaceful. Peace is the ability to prevent unrest from taking hold of you, regardless of external circumstances.
