And they do. Life exists in a balance of energy. If there is not enough energy reaching the field, it freezes, nothing grows. If too much energy, it drys up, too hot, everything dies. The energy tears away the water needed to have life work.
Life is a matter of things coming together and moving together.
Not on fire. You must have the proper energy balance for things to come together. On a very basic level, harmony is a matter of energy level. Harmony is two things moving as one. Add too much energy, and you will not have harmony.
