According to Osho, the 'perfection' of emptiness can't be achieved because it already is your inherent nature. Nothing human-made is perfect, but emptiness doesn't need making—only uncovering. Stop trying to fill yourself or to become perfect; drop all efforts. In the silent non-doing, you discover the ever-present, unerasable emptiness that was merely forgotten, not absent.
Stop trying to be perfect or to fill yourself; then you’ll notice the already-there empty space inside.
