Acharya Prashant explains that hidden motives in human interactions are not accidental but represent a continuous internal state. He uses the analogy of a hungry beast whose intention to hunt remains constant regardless of whether it encounters prey. Similarly, a person's underlying motives are always present and manifest in every action, even before a specific meeting occurs. He argues that if one is constantly dissatisfied with their current situation, it indicates they are searching for something else, and their mind is already occupied by that desire.
