Based on the vastu orientation of a site/structure, the affects on the occupants/owners, are told by a good vastu consultant,similar to an astrologer’s predictions depending upon a heroscope. Obviously the remedies also will be result oriented. So the vastu is observed even outside the india.
The rationality of vastu also colud be understood by a fact that vastu applies to the whole universe alike, just similar to the concept of the god , as omni present and omni potential,cutting across all the geographies,ethnics,languages etc..
why do wait further, rush to a good vastu consultant for defeating the agony and improving the happyness.
