Vastu Shastra
Vastu shastra (vāstu śāstra) is a traditional Hindu system of architecture which literally translates to "science of architecture." These are texts found on the Indian subcontinent that describe principles of design, layout, measurements, ground preparation, space arrangement and spatial geometry. Vastu Shastras incorporate traditional Hindu and in some cases Buddhist beliefs. The designs are intended to integrate architecture with nature, the relative functions of various parts of the structure, and ancient beliefs utilizing geometric patterns (yantra), symmetry and directional alignments.
Vastu Shastra are the textual part of Vastu Vidya, the latter being the broader knowledge about architecture and design theories from ancient India. Vastu Vidya knowledge is a collection of ideas and concepts, with or without the support of layout diagrams, that are not rigid. Rather, these ideas and concepts are models for the organization of space and form within a building or collection of buildings, based on their functions in relation to each other, their usage and to the overall fabric of the Vastu. Ancient Vastu Shastra principles include those for the design of Mandir (Hindu temples), and the principles for the design and layout of houses, towns, cities, gardens, roads, water works, shops and other public areas.
Industrial Vastu
The principles of the Vastu broadly remains the same and should be kept in the mind while preparing the building, constructing the building, installing the machinery, turning out the products and dispatching them to the clients. Even though there are vast differences in production methods or process flow etc. in different industries but the broad principles of Vaastu Shastra are universally applicable.
Office Vastu
It is a fact that not all shops in the same market do equally well, despite selling the same wares. Some shops that are in compliance with the vastu tips for commercial shops are more popular and appear to attract larger crowds. As a result, they do brisk business. Others, however, remain empty, despite alluring interiors and promotional gimmicks. We may think that the nature of the shop owners or their salesmanship skills makes them popular and win them, dedicated customers. But the location of the shop, exteriors including the slope and shape of the plot, placement of interiors, direction for the entrance, exit etc. also plays an equally important role in making a shop/business prosper.
Residential Vastu
Vastu means dwelling, the home for god and humans. Vastu shastra is based on various energies that comes from atmosphere like solar energy from sun, cosmic energy, lunar energy, thermal energy, magnetic energy, light energy, wind energy. These energies can be balanced to enhance peace, prosperity and success. If a house is made according to these principles, the inmates enjoy all the happiness in life. If it is against vastu principles, it will be a place for all sort of problems, worries and no peace.
