surfaces of the earth divisions (Bhooprishtas):-
According to vastu shastra, in order to find out whether the place is good for dwelling, earth has been divided in to 4 parts depending on itssurface. As per the results obtained from these surfaces of the earth, they have been named as Nagaprishtam, Gajaprishtam, Koormaprishtam & Daithyaprishtam.
A plot where the south and north direction have lesser length than the east west direction is called Nagaprishta bhoomi. When a house is constructed in such a plot, the north and south measurements should be equal and also other measurements should be regulated to make the plot square shaped. After that the position of the house should be decided. If the plot is not modified as stated above, the people involved in construction of the house and the in mates of the house may have face severe vaastu doshas. A plot modified accordingly will surely bring good vaastu results.
According to vastu shastra, a plot where the northern side is placed higher than the southern side and also starting from the southern end, when the plot reaches the vayu corner (vayu cone) the platform is elevated is called Gajaprishta bhoomi. Such a plot is found to be auspicious according to vastu shastra. No modifications are needed in this plot while constructing a house and also it brings prosperity, unity and long life to the members of the family.
As the name signifies a koormaprishta bhoomi plot has the centre portion elevated and the four directions are pushed outwards in a slanting position which resembles a tortoise. Such a property has a lot good vaastu results (vaastu gunas) in it. If a house is constructed on a koormaprishta bhoomi, it will bring unexpected economic progress, also stability in the family and mental peace.
A plot where the western side is lying low and the area from the Eesana corner (Eesana cone) to the Agni corner (Agni cone) is elevated can be termed Daityaprishta bhoomi. Such plots are considered to be not good for dwelling. Such a property will not give any good vaastu results and on top it may invite adverse effects also. Since the Daityaprishta bhoomi may invite vaastu doshas like danger to the children, loss of money, in fight in the family etc. it should be completely avoided in constructing a house.
