Acharya Prashant explains that the distinction between the internal and external worlds is merely a placeholder used in spirituality, as the two are fundamentally one. The internal self projects the external world, and the external world conditions the internal self; they are mirror images of each other. Because of this closed system, a person can only perceive what they already are. He uses the analogy of a lion that ignores a mobile phone because it does not belong to its world, illustrating that mere observation of one's current life is often useless because it only reinforces one's existing state. To achieve real change, one must observe not only their current condition but also something beyond it, such as the life of a saint or the vastness of the sky.
