Acharya Prashant explains that what individuals perceive as their personal likes and dislikes are actually products of external conditioning, environment, and upbringing. He illustrates this by pointing out that preferences for food or careers are often determined by the culture or family one is born into, rather than an innate choice. Our identity is constructed from these external influences, and the ego defends these preferences because it fears the emptiness that would remain if they were removed. He asserts that all worldly interests are essentially influences, and the true self or soul is beyond these artificial constructs.
