Both water and oil come from the earth. And though they are similar in many ways, they are opposites in their nature and their purpose. One extinguishes fire, the other gives fuel to the fire. Similarly, the world and its treasures are creations of God along with the soul and its thirst for spiritual truth. But if we try to quench the thirst of our soul with the wealth and pride and honors of this world, then it is like trying to extinguish fire with oil.
