Acharya Prashant explains the concept of irreversible transformation using metaphors from Rumi, such as a mirror never returning to iron, bread never returning to wheat, and a ripe grape never becoming sour again. He emphasizes that true change must be final and absolute, unlike the petty and superficial changes driven by the ego, which are often reversed. He describes authentic transformation as being like death or rebirth, where there is no possibility of returning to the old state. He warns that if one does not mature and ripen, they will inevitably rot, as there is no permanence in remaining 'green' or immature. Acharya Prashant further clarifies that spiritual maturity is not a gradual step-by-step process like climbing a ladder, but rather a dimensional shift similar to a satellite escaping gravity. He asserts that while natural processes can lead to physical death, they cannot lead to liberation. Liberation requires an intense inner thirst and a unique, self-created path rather than a pre-planned or mechanical procedure. Addressing the concept of impermanence, he notes that Lord Buddha taught that everything is momentary to encourage individuals to stop clinging to things that arise and vanish, and instead enter into that which does not perish.
