Every Living System survives on a continuous input of Energy from its environment. We take our food from other life forms. Each life form in turn derive their food from different specie. Life exists upon this Earth because of intricate and complex food chain.
Apart from Food, life also depends upon Solar Energy (Heat), Oxygen (Gaseous Energy), Water (Fluid Energy), Magnetism and Gravity (Earth), and Cosmic Energy (Space). The 5 subtle Tatvas or energy forms.
Vastu Shastra (Energy Science) tells us how best to arrange our affairs and life style to obtain optimum happiness (harmony).
An Energy System continuously emits energy waves through which it inter-acts with its surrounding Energy Systems. If the Energy Force Field with which it inter-acts is Positive, its Energy Field will be supplemented with energy, else it will supplement the other, itself undergoing strain and fatigue or energy depletion.
If you eat decomposed food, (Negative Energy Field), you will not gain nutrition available from food and may get sick. Similarly all other Energy Systems affect us – be it our clothes, furniture, building, etc.
Exposure to Negative Energy Force Field gradually causes stress, tension, and fatigue, dis-proportionate to our activity and situation in life. i.e. when you have worked for say 8 hours, you will be tired as if you have worked for say 12 hours in a day. Increased stress, tension, and fatigue, will cause energy depletion and symptoms of dis-ease, ailments, and dis-orders, in that organ or organ system, which is weak to begin with. When you consult a doctor he will be treating the symptoms and not the root-cause, about which he is totally unaware.
Even if the dis-eases, ailments, and dis-orders, are genetic, or due to an obvious infection or injury, the Negative Energy Force Field will cause retardation in the healing process.Energy input through all our 10 senses affect us and the study of these effects is Vastu Shastra (Science).
