To percolate means to filter slowly through a porous surface or substance. We do this every day to ourselves and we don’t even realize it is happening.
What sort of things are you filtering in through your eyes, your ears, your nose and your mind today? Are you filtering your world from a sense of pain? This will only cause more pain.
What we percolate through will inevitably run through our entire life. We must percolate through good things to get good results. If you percolate coffee through a machine that has been cleaned but not rinsed, you will get the cleaner taste in your coffee. It is the same for all of us. What are you letting in today?
