By corollary there is pain in forcible seperation between two harmonious energy systems. So some persons don't enjoy sweet taste and some others don't enjoy bitter taste - because the sensory currents present in their taste buds do not match with the frequency of sweet or bitter tasting food products. When one is sick, the sensory currents recede due to increased levels of toxicity in the body so the best of foods do not taste good. We celebrate when birth takes place and remorse at the time of death of a beloved. In birth there is union and in death forcible seperation.
Energy flows from the higher to the lower system.
Therefore all our interactions that are downward and outward with other people or places or things depletes our energy whereas our inward and upward interaction with the superior energy force during meditation supplements our energy nucleus. For happiness in life and for improved life performance, meditation is therefore the best and the only total remedy. Meditation is best performed within pyramid space. Pyramids are known to have maintained even dead body cells in harmony for over 5,000 years after death. There is no energy system in the world as of date that can equal this feat.
