Energy systems are bi-polar. Every energy system has a positive and a negative pole. Positive cannot exist on this plane without negative. Harmony between positive and negative is important. Positive pole gives out energy waves.
Negative pole receives energy waves.
So give and take is fundamental, to all life forces. Harmony between what we give to others and what we take from others, can alone result in happiness. Billionaires and pavement dwellers are both unhappy. In the past billions of years, the history and our experience shows that happiness is conspicuous by absence. Whereas most of our time, energy, and attention are for the pursuit of happiness, the result is mostly Frustration, Stress, Tension, and Fatigue.
