If corrections and alterations are made in these things as per the Vastu shastra i.e. the Edifice Science all the flat holders can be benefited as well. The profits and losses are 20% in excess to those who live on the ground floor as compared to others. This is because they are attached to the ground; therefore, the ultra-violet rays of the sun and the cosmic rays act to a larger extent to those people.
The overhead water tank on the upper most slab of the building is also very important. It is good if it is situated in the west, the south-west and the north-west direction. It is not proper if it is situated in the south-east, the north-east, the east or the north direction. These days, this tank is taken at the centre of the slab which is the place of Brahma. The tanks are given circular, pyramidal and other shapes which is totally wrong. The weight should never be concentrated at the place of Brahma. If it is so, one has to face innumerable calamities. In that case it is better to take the decision of leaving the flat. All the flat holders in the building should think over it seriously and find a way out.
