How & where did it originate?
According to mythology, Vishwakarma the celestial architect was abducted by Ravana to build Lanka as per Vaastu. Shri Krishna engaged the services of Vishwakarma to build Dwarka. Pandavas at the behest of Shri Krishna prayed to Vishwakarma to build Indra Prastha. Hence, it follows that Vaastu is as old as Vedic ages.

For whom is Vaastu meant?
Vaastu is meant for the entire humanity irrespective of caste, creed, race, nationality, colour, and religion.

Is Vaastu meant for Hindus only?
Vaastu is meant for Hindus and Non Hindus alike.

Is Vaastu easy to follow or complicated?
Vaastu is a definite science based on well-established principles. It therefore follows that once the basic principles are well understood Vaastu is as easy as any other subject of human knowledge. Even if it is complicated the advantages make it worth the complication if at all there are any.

Is Vaastu is applicable only in India?
Vaastu is not only applicable in India but all over the world.

Can Vaastu apply to apartments?
At first sight although it appears to apply to apartments, there is a school of thought, which insists that each dwelling should be separated from its neighborhood by a reasonable distance to ensure good flow of air for ventilation and plenty of light from all sides. Vaastu therefore appears to frown upon the very concept of apartments since they almost always share common walls.

Does Vaastu have relation with health?
The prime requirements of man are the driving factors for Vaastu. Hence health most obviously is one of its prime concerns.

Is Vaastu expensive?
Vaastu as such is meant for the ultimate benefit and thus the question of being expensive does not arise.

Does Vaastu improve relationship?
Invariably yes. Nearly 75% of the Vaastu clients insist this prime requirement in particular. Be it marital or any other filial bondage Vaastu undoubtedly promotes the ties.

1. Hand length of the owner
   
2. Palm length of the owner
   
3. There are totally eleven types of sophisticated calculations, which a dwelling has to satisfy.

Positive Vibrations:- if L is length B is breadth L* B =A where A is Area

Formula = P= A*B/12 where P is the remainder representing the positive vibrations

Negative Vibrations:- if L is length b is breadth L* B =A where is Area

Formula = N= A*3/8 where N is the remainder representing the vibrations Note: - Positive vibrations should always be greater than negative vibration P>N

1. Dhwaja Aya (Flag ratio) L*B = A where A is the area
   Formula A* 9 /8 the remainder should be 1 which is flag ratio. A dwelling with this ratio has been recommended in our Vaastu texts.
   
   
2. Dhoomra Aya (Smoke ratio) L*B = A where A is the area
   Formula A*9/8 the remainder should be 2 which is smoke ratio. A dwelling with this ratio has not be recommended in our Vaastu texts.
   
   
3. Simha Aya (Lion Ratio) L*B = A where A is the area Formula A*9/8 the remainder should be 3 which is Lion ratio. A dwelling with this ratio has been recommended in our Vaastu texts. But there is school of thought according to which the house opposite to a Lion ratio will be destroyed. However all agree that all temples should be build only in Lion ratios
   
   
4. Shwana Aya (Dog Ratio) L*B = A where A is the area Formula A*9/8 the remainder should be 4 which is Dog ratio. A dwelling with this ratio has not been recommended in our Vaastu texts.

Vrishabha Aya ( Bull Ratio) L*B = A where A is the area.

Formula A*9/8 the remainder should be 5 which is Bull ratio. A dwelling with this ratio has been recommended in our Vaastu texts.

Khara Aya ( Devil Ratio) L*B = A where A is the area.

Formula A*9/8 the remainder should be 6 which is Devil ratio. A dwelling with this ratio has not been recommended in our Vaastu texts.

Gaja Aya ( Elephant Ratio ) L*B = A where A is the area.

Formula A*9/8 the remainder should be 7 which is Elephant ratio. A dwelling with this ratio has been recommended in our Vaastu texts.

Kaka Aya ( Crow Ratio) L*B = A where A is the area.

Formula A*9/8 the remainder should be 8 which is Crow ratio. A dwelling with this ratio has not been recommended in our Vaastu texts.

1. All odd numbers produce results good for construction of a house.
2. All even numbers yield bad results although there is a school of thought that Smoke ratio is good forkitchen.
3. Dog ratio is good for tool rooms, and armoury where weapons are stored.
4. Devil ratio is good for kennel and stables etc.
5. Crow ratio is good for toilets This school of thought also recommends.

flag ratio for bathroom
Lion ratio for bed room
Bull ratio for dining room
Elephant ratio for treasury, chase and valuables
All rectangles with odd lengths and odd breadths are good

1. All squares with odd sides result in flag ratio, which is very good.
2. Where as all other ratios have there own sophisticated rules and formulas for doors windows ventilators and direction, the flag ratio, has however been exempted for these restrictions. However doors, windows and ventilators in all cases should be not only even but also a maximum of eight or it’s multiples.
3. A house with lion ratio can face a flag ratio.A house of flag ratio can face a house of  bull ratio or be behind a  house  of bull ratio. If elephant ratio faces lion ratio it is good for the lion while bad ratio for the elephant ratio. Elephant ratio however can be at the right of a lion ratio which is good for both. Bull ratio should never be behind an elephant ratio. Bull and lion should never face each other. Flag ratio should never be at the left of lion ratio, which will result in the death of some one in the house of lion ratio.   Lunar divisions( thithi) Moon's orbit around earth is divided into 30 equal divisions of 12 degrees each; each division is known as a thithi ( T). If area is A Formula A*8/30 = T (Good = 2, 3, 5, 7, 10,12, 13, Bad = 1, 4, 6, 8,9, 11. 14, 15, and 0) Weekly division if area is A and W is weekly division the formula is as follows W= A*9/7 If the remainder is
4. Sunday = Fear of fire
5. Monday = Much property
6. Tuesday = Loss due to burning
7. Wednesday = Wealth and Good food
8. Thursday = Popularity

Vaastu and Soil testing
Before construction the soil has to be tested for its worthiness and only after the positive results are obtained the construction can be started   accordingly.

1. If there is no water left and it is observed that the pit is dried and cracked the plot is unworthy for construction of any building.
2. If water is retained the plot is ideal for construction ( the more water retained the better).
