The Five Elements

Vaastu is the science of direction and architecture that puts together the five elements of nature and adjust them in harmony with the man and the material. Vaastu Shastra is creating a congenial settings or a place to live or work, taking advantage of the benefits bestowed by the five elements called "Paancha Maha Bhootas" of the nature thereby producing positive energy that enhances health, wealth, prosperity and happiness in a spiritual environment.

Vaastu in Building:

Vaastu Shastra prescribes favourable forms or shapes for sites and buildings based on flow of energy. Many of the rules are attributed in a way that they are in line with the cosmos creation - the sun's path, the rotation of the earth, magnetic field, etc. The sunrise and morning sun is especially beneficial and purifying and hence the East is a treasured direction. The body is considered a magnet with the head, the heaviest and most important part, being considered the North Pole and the feet the South pole. Therefore sleeping with one's head in the North is said to cause a repulsive force with the earth's magnetic North and thus is harmful.

Vaastu in Health:

When we talk of Vaastu and health, we need to relate Vastu with Ayurveda. By intertwining the two subjects we will be in a position to understand the different diseases and health problems and how by certain Vaastu corrections we could treat the diseases or ailments better for giving faster relief to the patients.

The Air principle: created from ether and air. A Vata person can be prone to chronic constipation,back pain (normally lower back), paralysis, arthritis, etc.

The fire principle: Created from fire. A Pitta individual can be prone to rashes, itches and be susceptible to liver disorders.

The Water Principle: Created from water and earth. A Kapha individual can be prone to congestion of lungs, obesity, bronchitis, sinusitis and cold related ailments.

These three basic problems also called tridoshas, three bio-energies or biological humors, build and nurture the body and carry out the biological functions of an individual. The augmentation or decline of one or more of these doshas upsets the biological functions and disease sets in.
