Acharya Prashant explains that jealousy is fundamentally rooted in comparison, which is only possible for things that can be quantified or measured, such as height, weight, marks, or income. He clarifies that while it is natural to compare numbers, the problem arises when an individual identifies their personal worth with these figures. If a person believes their value is defined by the percentage they score or the money they earn, they become susceptible to suffering. He emphasizes that while physical attributes are measurable data points, the individual's true essence cannot be expressed through numbers. He further explains that concepts like love, joy, freedom, and truth are immeasurable; one cannot quantify how many kilograms of love they feel or how many feet of joy they experience. Anything truly real or heartfelt has no scale or limit. Therefore, the true self is infinite and beyond any numerical value or boundary. He advises that one should measure what is meant to be measured, like goods in a market, but should never measure their own self. Jealousy occurs when a person creates an artificial link between their incomparable self and measurable external factors. Finally, he discusses how feeling inferior to someone greater and feeling superior to someone lesser are both manifestations of the same ego-driven comparison. He warns against deriving satisfaction from being better than others, as this mindset inevitably leads to feeling small when encountering someone superior. True peace comes from recognizing that the self is stable, eternal, and beyond the changing numbers and prestige of the material world.
