Vastu shastra :
Vastu shastra (vastu sastra, also vastu veda and vastuvidya, "science of construction", "architecture") is an ancient doctrine which consists of precepts born out of a traditional view on how the laws of nature affect human dwellings. The designs are based on directional alignments. This ancient Indian science of structure recommends principles of layout and planning including landscaping – that are valid even today!

The Vastu Purusha Mandala is an indispensable part of vastu shastra and constitutes the mathematical and diagrammatic basis for generating design. It is the metaphysical plan of a building that also incorporates the presence of supernatural forces. Purusha refers to energy, power, soul or cosmic man. Mandala is the generic name for any plan or chart which symbolically represents the cosmos.

The Vastu Purusha is the presiding deity of any site. Usually he is depicted as lying on it with the head in the northeast and legs in the southwest. Vastu shastra prescribes desirable characteristics for sites and buildings based on flow of energy – depending on directions. Earth, Water, Fire, Air and Space are the five elements or ‘panch mahabhoota’ that remain at the core of the science.

Many people have tried to understand and implement the old principles to the new way of life. The science of structure has been adapted to even apartment blocks; where the site is taken as a micro-site and modifications are done to make the micro-site in accordance with the guidelines of Vastu shastra. This enables people to dwell/work in Vastu-compliant homes, offices and factories.

Feng Shui:
Feng Shui is a Chinese philosophical system of harmonizing the human existence with the surrounding environment. The term feng shui literally translates as "wind-water" in English. The Feng Shui practice is based on harmonious coexistence between the Universe, Earth, and man – with the help of Qi/Chi/Energy. Qi rides the wind and scatters, but is retained when encountering water.

Historically, feng shui was widely used to orient buildings—often spiritually significant structures such as tombs, but also dwellings and other structures—in an auspicious manner. It is of particular significance in building interiors; and promotes harmonious living/working through the placement of objects in a manner that good energy or ‘chi’ circulates freely in the premises. Balancing ‘yin’ and ‘yang’ is also significant in Feng Shui.

The most popular emblem of Feng Shui is the Laughing Budhha – the plump and gregarious Chinese monk who is said to bring health and prosperity to its owners. Also other animal figures like dragons, frogs and tortoises have their own significance in the numerous interpretations of this theory.
