Acharya Prashant explains that human life is deeply rooted in duality, which begins at birth with the distinction between the self and the world. This duality is further reinforced by language, which creates a divide between objects and ideas, and by organized religion, which separates the creator from creation and suffering from bliss. He argues that this constant training in duality prevents direct observation, leading individuals to perceive everything only through comparison and conceptualization. Concepts like 'black' or 'white', 'man' or 'woman', and 'good' or 'bad' are interdependent, meaning we do not truly know what anything is in itself, but only in relation to its opposite.
