Acharya Prashant explains that the human desire to return to one's roots or past is actually a deep-seated longing for the source of existence. People often mistake this for a desire to return to childhood or a specific geographical location, like the mountains, because these represent the earliest memories closest to the 'zero' or the void from which consciousness emerged. He clarifies that childhood is cherished not for itself, but because it is the neighbor to that which existed before birth. One must not get attached to the symbol or the 'letter'—such as a mountain or a memory—and mistake it for the ultimate truth, as this leads to isolation from the rest of the world and a failure to reach the essence.
