Instead of attacking a problem head on, looking at a problem in terms of what is lacking is an important step toward finding an eventual solution. However, there is another part to the formula. To be effective, you can’t simply apply a solution to a problem on the same level as the symptoms of a problem.
For example, you notice that a plant has withered leaves. It is not enough to determine that the leaves are lacking water. If you attempted to solve the problem on the level of the symptoms of a problem, you’d apply water to each individual leaf. Clearly that is as ineffective as it is time-consuming.
Solutions must be applied at a more fundamental level than the problem. In this example, watering the root and letting the sap (a more fundamental aspect of the plant) nourish the entire plant.
Solutions reside at subtler, more fundamental levels than where problems are manifesting. The tumor is a manifestation of something deeper. Treating a tumor on the surface of the tumor is not as effective as addressing the root cause of the tumor. That must be done at a much subtler, more fundamental level than the tumor itself.
“The significant problems we face can never be solved at the level of thinking that created them.” Albert Einstein
