Human beings have a natural and emotional affinity with the earth. The earth     revolves around the sun and has gravitational and magnetic force. Scientists have proved that the earth is a huge magnet with two poles — north pole and south pole. It has also been proved that the human body is a magnetisable object with a large percentage of iron in the blood.

As all know, opposite poles of a magnet attract each other and same magnetic poles repel each other. The Vastu principle of placing the head in south direction while sleeping is based on the earth’s magnetic property. Our ancients have found that sleeping with the head towards the south enables one to go with the nature and draw maximum positive energies from the cosmos to keep fit and healthy. Vastu also deals in detail about inspection of soil, selection of site, shape, shape and size of plot to land.
 

After earth, water is the most important element. It is linked to our senses of taste, touch, sight and hearing. It is quantitatively the largest of the five elements, as more than 80 per cent of our body and two-third of earth’s surface is water. Most ancient civilisations came up close to rivers and water sources.

Vastu provides important information about the placement of water sources like wells, boring, underground water tank, overhead water tank etc, while planning the house. Positions for drainage of water, septic tanks, sewerage, drains etc. are decided carefully to optimise the benefits of water element.

Sun is the most vital source of energy and light. It is the soul of the universe. Formation of day and night, charge in seasons is brought about by the movement of the Sun in relation to the movement of the earth. The fire element is related to our sense of sound, touch and sight. It is difficult to imagine life on earth without the sun. The sun’s rays can be split into 7 plus 2 colours. Beginning from the very beneficial ultra-violet rays in the eastern side corresponding to north-east, the sun’s rays further split into violet, indigo, blue, green, yellow, orange and red (VIBGYOR) and intra-red in south-east. Violet and cold colours of the spectrum have a beneficial and soothing effect on the body and hence it is recommended to keep open space in the north-east.
When these rays combine with water, they get additional benefits. It is, therefore, recommended to have a water source in north-east direction. To block north-east by building a toilet there is depriving yourself of most beneficial rays of the sun and has adverse results. The ultra-violet rays normalise the metabolism of the body.
The supreme wisdom of our sages is reflected in the ancient ritual of Surty Namaskaar wherein the beneficial rays of the sun become more potent when seen through fresh water offered to the sun god.

The air is vital for our survival. Our sense of sound, touch and feel are related to air.
The air on earthis a mixture of various gases like nitrogen, oxygen, helium, hydrogen
etc.Oxygen is vital for human beings and nitrogen is essential for the growth of plant
life which in turn provides oxygen.
Correct percentage of different gases, atmospheric pressure and humidity level is
important for life forms on earth. Vastu recommends proper placement of doors,
windows, ventilators, balconies, height of structure and placement of trees and plants
for balancing the air element within the structure.

Aakash or space is infinite and limitless. It is related to our sense of hearing. In a house, the space element is related to the centre portion or the brahmasthan. It is important that brahmasthan be kept open and light. Any disturbances in the space element are detrimental to your growth. When you keep your office, home or factory in a mess, you spoil the space element around you.

Extra construction, unutilised rooms or floors, homes stuffed with possessions, too big extravagant and opulent houses collect a lot of negative energy. It is recommended to build only the required area and no more. A balance of the primary elements in the house brings you closer to nature and creates balance and harmony leading to peace and property.
