The atmosphere contains all the elements needed to sustain life: earth, water, fire, air and ether. In anything material, all these elements are present. For example, in my body there is water, although you cannot see it. Similarly, you don't see fire in my body, yet my body is warm. Where does this warmth come from? You don't see any fire. Do you see any fire burning in my body? Then where does the warmth come from? What is the answer?
