According to vaastu sastra, the world comprises five basic elements known as the pancha maha bhoota. Out of the nine 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 nothing but water with haemoglobin and oxygen.
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.
