Just like an electrician-he knows how to utilize electricity for the refrigerator and the heater, although the heating process is just opposite of the cooling process. We see opposite. Similarly, material nature and spiritual nature, just opposite, but the same way: the electricity utilized for heating and electricity utilized for cooling, the energy is the same, but it is the manipulation of the engineer which can turn heat into cold and cold into heat.
