Why it is so, is hard to explain. Scientists working in this field have suggested that this may be due to the fact that the process of manufacture of Aluminium from Bauxite involves tremendous amount of power compared with the power consumed in the extraction of other metals. It is suggested that due to this phenomenon the energy some how gets trapped inside the metal whichmakes it resistant to Cosmic Forces.

One should therefore be careful while using aluminium sheets and Aluminium doors as its effects are yet to be studied as far as Vaastu is concerned. At the same time we cannot lose sight of the fact that Aluminium opens the door for exciting experiments in the field of Vaastu, especially where corrections of the defective buildings are to be made and demolitions are not easy due to the cost factor. If only we can determine the points where we can block the negatively strong energy forces we may open yet another way for Vaastu corrections.

Now if we examine the placement of doors and gates as explained earlier, you will readily see the reason for doing so. If the door is in the proper places as mentioned above and is opening in the right manner when you enter then the energy forces from the positive side are the first to gain entry, which is highly recommended, since it allows periodic replenishment of increased density in the enrgy field inside the structure and maintain a strong current from the entry to the exit point.

If on the otherhand the door opens to allow the negative forces to gain entry first obviously the advantage is lost and the house is denied of the best benefits.
