If the water in a pot of rice is not fully dried, even if you skim the top that seems dry, you will still have unnecessary water in your plate of rice.
If the water in a pot of rice is fully dried up, even if you scoop the bottom, you will have no unnecessary water in your plate of rice.
If a system is tainted, even if you skim those that have risen to the top, they will carry with them some of that taint.
If a system is pristine, even if you explore the lowest places, you will still find that originality.
