According to vastu sastra, the world comprises five basic elements known as the pancha maha bhoota. Out of the eight planets, ours has life because of the presence and balance of these five elements. The five elements are as follows.
EARTH (Bhumi) - Earth, the third planet in order from the sun, is a big magnet with North and South poles as centers of attractions. Its magnetic field and gravitational force has considerable effects on everything on the Earth, living and non-living.
WATER (Jala) - This is represented by rain, river, sea and is in the form of liquid, solid (ice) and gas (steam, cloud). It forms part of every plant and animal. Our blood is mostly water.
AIR (Vayu) - As a life supporting element, air is a very powerful life source. Human physical comfort values are directly and sensitively dependent on correct humidity, air flow, temperature of air, air pressure, air composition and its content.
FIRE (Agni) - Represents light and heat which account for day, night, the seasons, energy, enthusiasm, passion and vigour.
SPACE (Akasha) - The Akasha provides shelter to all the above elements. It is also considered the primary conductor of all energy sources within the universal context – physical energies such as sound and light, social energies such as psychological and emotional, and cognitive energies such as intellect and intuition.
These elements are affecting the animate and inanimate objects knowingly or unknowingly. The effect of these elements are observed on the Earth to a larger degree than the other planets. The nature on Earth is made up of these five basic elements. The elements maintain a regularity and balance in nature. If the building meant as a residence for the defence of the wisest animal i.e. man, is constrtucted with due regards to the elements, the infinite forces and powers of the nature are obtained by him, his life is full of peace and prosperity. All these elemnts are not found together on any other planet except the earth and probably that is why life and nature do not exist there.
