Vastu is a vedic science. By adopting the principals of Vastu any body can bring remarkable positive changes in his life. Construction with proper Vastu shows proper balancing with the natural powers. Energy level of any person can be increased by following the proper rules of Vastu during constrction of a house or commercial place. Vastu is one of the best gift given to us by our ancient Vedas. In short Vastu is a science to make life better. In beginning I would like to tell you Vastu can not change the destiny of anybody completely but may be helpful in increasing positive results. Vastu accepted all over the world and proved extremely beneficial. Building constructed following the principals of Vastu are the representation of truth, acknowledgement of the cosmic powers. Homes, offices and other buildings are planned through the sacred measurements and orientations, to be resonant with the cosmic energy matrix of the universe and therefore if done by an EXPERT, the structure becomes alive, floods with healing and nourishing powerful energies. Your life, your karmas change for the better. All measurements are related to a sacred Vastu Purush Mandala and must be calculated for your birth star and for all auspicious effects.
Vastu is a science not a superstition, basics I which are orientation, auspicious entry, room locations, Brahmasthan, measurements and geometry. Vastu has a lot to do with mathematics also but nothing with numerology. In every room of house you always activate its presiding deity and corresponding energy. The structure and orientation of the building sets up a vibration that either Benefic, malefic or may be neutral.
The structure you live in must have some effects irrespective of the matter who own it. If you really wants to live with proper alignment of Vastu, then never sacrifice with impure vastu residence or office. Room placement, entrance are very small as per as I vastu which is a deep, complex mystic and powerful ancient science.
