Healing is like a profit and loss industry. Count how much costs you have. How much Qi do you spend on digesting your food, thoughts and emotions? How much Qi spend late stay on, exercise and work too hard?
When people say they need exercise, they run on a treadmill. Sometimes they wear shorts and run outside at iron weather or sweat while they run into the extreme heat. You spend Qi when you run, so how much energy can you win by running? The costs are too high.
The same concept applies to healing. Holding on negative emotions requires Qi. You don’t have to hold emotions. Once you have experienced them, let them go. They are not yours to hold.
