Ayurveda is all about living in harmony with nature and self. Five-element theory of Ayurveda is also the basis of Vastu. When man started habitation in enclosures, groups and villages, the divine science of Ayurveda and Vastu came in handy for making suitable structures in sync with life around the planet while respecting nature.
Like Ayurveda Vastushastra or Vastu veda is also a divine knowledge. We can live a healthy and happy life by respecting laws of nature and mother Earth. Five elements Earth, Water, Fire, Air and Sky represent macro forms of cosmic energies. These energies manifest themselves in subtle forms in almost every living or nonliving thing. These energies are the basis of life, without respecting the source we just can't go on reaping the benefits. Sadly current behavior of mankind is like an irresponsible and unwelcomed guest in the house, who always tries to get petty benefits at major cost of host. This relationship is going to be sour sooner or later and guest will be the person who will get maximum burnt out of it.
Vastu is the divine science which guides us to respect the five elemental force present in subtle form around us for mutual benefit. Now a days Vastu science is representing merely the directions for material prosperity. It is losing the whole agenda of health and peace for mutual benefit of the whole cosmos.
Vastu science in Ayurveda gives the details of how we can achieve the maximum benefits of cosmic energies without disturbing its natural flow. How we can make recovery rooms or health projects. Ayurveda talks about body types according to their subtle five elemental presentations in body. Some people have more sky, air, fire, water or earth qualities in them as compared to others. To keep them in balance one need to understand the presence of five elements around them. These macro forms of elements in nature have effects on health. These long standing disturbances can become psychosomatic diseases later.
To understand it better Acharays of Ayurveda have mentioned three types of land.
Aanup Jangal Sadharan
Jangal land is more airy, windy and dry. So more Vata disturbances can happen in the population. This type of land has small and sparse trees. Water is less and deep seated or with low underground water tabs. This type of land can cause heat and drying problems along with joint problems. This type of land is in deserts, like Bikaner, Jaisalmer in India and Arab countries. People who migrate suffer more than the natives because of their genetical make up is according to the land of their ancestors.
Aanup desh is humid land. Acharya Charak explained this type of land is full of rivers, water tabs, mountains and hillocks. It has more trees and is nearer to sea. Residents of this land may suffer from Kapha and Vata problems. Assam, Bay of Bengal and Kuchh are the examples of this type of land. If we understand the natural quality of the land we can take care of the structure or building to minimize the subtle effects on residents. So people with too much heaviness and blockages in the body are going to suffer more in this type of land.
Sadharan desh or land has all the factors in equilibrium. Thus all three humors of body like Vata, Pitta and Kapha remain in equilibrium. This land has weathers like summer, rains, winter and autmn. Planes of Ganges in India are good example of this type of land. People living in this type of land are healthy and strong.
Once we know the type of land we can understand its effects on health easily. If some one has too much earth or water qualities in body he/she needs to make some changes either in the place or building design or diet and life style to negate those extra effects on health. These effects of land on human body are tremendous and can attribute to genetically compromised generations.
