Vastu shastra (vāstu śāstra) is an ancient Indian science of architecture and buildings . These are texts found on the Indian subcontinent that describe principles of design, layout, measurements, space arrangement, ground arrangement and spatial geometry. Vastu Shastras incorporate traditional Hindu and in some cases Buddhist beliefs. The designs are intended to integrate architecture with nature and ancient beliefs utilizing geometric patterns (yantra), symmetry and directional alignments.
A home other than being only a house to live, it is an increase of our mental space and indication of our identity. Every part of our life is profoundly laced with the design, decor and maintenance of our home. Vastu Shastra depends on different energies that originates from atmosphere like solar energy from sun, cosmic energy, lunar energy, thermal energy, magnetic energy, light energy, wind energy. These energies can be adjusted to upgrade peace, prosperity and achievements.
The building which is constructed with the norms prescribed by Vaastu is beneficial from every angle. It creates healthy environment which is essential as it supports in health, destiny, harmony (in short everything).
But if the building is made against vastu principals, it will be a spot for all kind of issues, stresses and no peace.
