Ether (Space) Akash
Space is that element of nature which is the most widely spread. Space is endless and spreads up to eternity. There is no place in the universe where space does not exist. Gravitational force, magnetic force, radio active rays, infrared rays, ultraviolet rays, light rays and the rays coming from the planets are all present in space. Even the gift of sound is given to us by this element of ether. Without this element sound is not possible. Sound is produced by the vacuum of the space, medium of the environment and air. A house or a building acquires its element of ether in proportion to the height of its walls.
The dome of a temple or a Gurdwara and the arch of a mosque symbolises abundance of ethereal element. If walls of a house are low in height, then one gets a feeling of suffocation due to lack of ether element. In such a situation ether element does not develop fully in the body. Therefore we should construct the house in such a way so as to get maximum benefit of the visible and invisible energies of the nature.
Plants and living organisms get their life from air. Air awakens virility and vitality. Just as air regulates and maintains our body, in a similar manner it also regulates and maintains the healthy atmosphere of a building. The earth is covered by a layer of gases. This covering of gases is known as the atmosphere. The atmosphere is made up of different gases in different proportions. 78% of the earth's atmosphere is made up of Nitrogen, which is necessary for the growth of all vegetation. 21% of the atmosphere is made up of oxygen which is essential for life. It makes up about 1/5 of the atmosphere. The other planets do not have oxygen and with the result they do not have life as well. Carbon is present in a small quantity of 0.03% in the atmosphere in the form of carbon monoxide (CO) and Carbon Dioxide (CO2). Apart from these there is 0.93% of Argon, 0.01% of hydrogen and 0.01% of other gases present in the atmosphere. Concentration of the heavier and essential gases is only up to about 5 kms. from the earth. At about 16 kms from earth, due to the influence of Sunlight, oxygen gets converted into ozone. One molecule of Ozone contains three atoms of oxygen. This layer of ozone is most dense at about the height of 23 km. from earth. The Ozone layer is very important because it protects the earth from the harmful radiations emitted by the Sun. If the Ozone layer gets depleted or damaged, then the temperature of the earth tremendously and earth will face the fear of extinction.
The ice will start melting and a fear of inundation will be created. Generally during day time the plants absorb carbondioxide from the atmosphere for their photosynthesis and release oxygen, this process is reversed during night time. They start absorbing oxygen and releasing carbon dioxide. Peepal tree is the only exception to this rule. Carbon dioxide is harmful for us, and so we should not sleep near the trees at night.
Extremely auspicious ultraviolet (parabaingani) rays enter through the Ishan kona. Pollution in this corner produces carbon dioxide, nitrogen and other harmful gases which reduce or eliminate the effect of the ultraviolet rays.
The building should not be near a cremation ground
Cremation of the dead body produces carbon and other harmful gases. These have a harmful effect on human life.
Sound and touch are two special qualities of air element
Touch produces sensation, which in turn produces awareness or consciousness. Consciousness finally produces an action or reaction. This is the reason for our instant reaction to the chill of winter or the heat of the westerly winds of summer.
Air as an invaluable gift of nature
Air is an invaluable gift of nature to mankind. Air flows into the building through its doors and windows. For this reason special attention should be paid to the air inflow at the construction stage. In India North direction should be left open for the inflow of air. There should be plenty of windows and ventilators for cross ventilation in the house.
Sun is our main source of energy. Solar energy gives us heat and light. Heat basically is a form of fire. The Earth rotates on its axis and also revolves around the Sun. These movements of earth are the reasons for day and night and for the formation of seasons. The heat and light of Sun along with wind and rain gives strength, vitality, courage and enthusiasm to the living beings on earth. Most of the colonies and settlements in the world have been constructed in such a way so as to allow optimum inflow of solar energy into the house. However as per the maxim 'Excess of anything is bad', excess of Sun's heat in the house is also bad. People living in East facing houses in the hilly regions keep facing the woes of too much heat. By the afternoon the scorching heat of Sun really heats up their houses and makes them very uncomfortable. Hence the fire element should be organised in such a way, that the house remains warm in winters and cool in summers.
