Ayadi Calculation (Ayadi Shadvarga)

  1. Ayadi calculation is one of the most important part in Sthapatya Veda, Ayadi Calculation is also called as Ayadi Shadvarga or the building formulae. The Scriptures as well as the ancient architects (Sthapatis) considered the dwellings as a living organism, irrespective of temple, residential homes, palaces etc.
  2.  The Land also known as Ksetra and the dwellings was built in proper rhythm & proportion for the residents to live in harmony with nature. When houses were built using these Ayadi formulae, they were said to give the residents spirituality, health, wealth and prosperity.
  3.  There are different calculations done in Vaastu for different purposes using Ayadi Shadvarga to check the energy suitability of the residents with the land & building by taking into account the Nakshatra or the birth star of the owner, these calculations are used for Town or city planning, Temples, Residences, Apartments, Commercial & Industrial buildings.
  4.  There are six aspects to be examined under Ayadi

1. Aaya – Income / benefits

2. Vyaya – Expenditure

3. Yoni – Direction indicating the flow of energy (Prana)

4. Varam – Weekdays

5. Nakshatra – Star

6. Amsa – Quality / feature

 The Process of calculation for each ayadi



Perimeter of Building x 8




Perimeter of Building x 9




Perimeter of Building x 3




Perimeter of Building x 9




Perimeter of Building x 8




Perimeter of Building x 4


 The Aaya (Income) should always be more than Vyaya (Expenditure). If Vyaya is more than Aaya, then the residents will always have financial problems.

 The Yoni Should always have reminder in odd numbers i.e 1, 3, 5, 7. Refer the below Yoni table for benefits.

Amsam or Quality with the remainder 2, 3, 4, 5, 7, 9 are considered auspicious.

The above calculations are performed by an expert Vaastu sthapathis, before one starts construction of any form of building, it is recommened that You consult an expert to attain both spiritual & material benefits.

Yoni calculation is an important aspect in Ayadi calculation, based on the Yoni the direction of the plot & Building is decided. Dhwaja Yoni is considered the best Yoni in Sthapatya Veda. Another important point to be observed is that all the auspicious Yonis are in line with Cardinal direction of North, South, East & West. The Plot or the building with diagonal directions  & entrance from North-East, South-East, South-West, North-West is inauspicious & hence rejected.

 Ayadi is a technological application for building design and construction.

“Adi – Ay” stands for “to analyze the primal energy “Adi” => “Ayadi” or calculation of wave length (in a form of concentric squires) and to find positive benefits.

The perimeter of the primal energy particle, Paramanu was measured and used as proportional base in building’s perimeter calculations.

The perimeter is the measure of consciousness.

It can be positive or negative. When using Ayadi, only positive measures (numbers) are used in the building construction.

These numbers are “auspicious.”


“Every living being possesses qualities and characteristics of a particular star at the time of birth – Birth Star.”

“To find the number relating to each star and analyzing its wave length as good and bad comprises the essence of ‘Ayadi Gananam.’”

Varam with 1, 2, 4, 5, 6 is auspicious

There are 27 Nakshatras in Vedic astrology, the nakshatras with 2, 4, 6, 8, 9 as remainders are auspicious.

That number or wave length of the building’s perimeter will match the Birth Star’s wave length or inhabitant’s wave length creating resonance and harmony of both.

Different types of Ayadi calculations involve different aspects:

  • ·       6 Major aspects – SHADAYADI
  • ·       10 Major aspects – DASAYADI
  • ·       16 Major aspects – SHODASAYADI

Shadayadi is good for domestic construction.

Shodasayadi is good for temples and deities.

  • ·       Aayam (income)
  • ·       Vyayam (expenditure)
  • ·       Yoni (direction of energy waves)
  • ·       Varam (day of a week)
  • ·       Amsam (quality)
  • ·       Nakshatra (birth star)

Ayadi Practical Application

The perimeter of the building is most important measure to create vibrational resonance of all involved energetic spaces:

  1. 1.         Cosmic
  2. 2.         Earthly
  3. 3.         Encapsulated Building’s Space
  4. 4.         Human’s inner space

Per Ayadi tables, Encapsulated Building’s Space has its own Star based on the perimeter of the building.

Every inhabitant of the building has his/her own Birth Star too.

Per Ayadi, the birth star of a female has to be in resonance with the building’s space first.

When the relational number is found between stars (building’s and female’s) from Nakshatra Table, and then that number should be verified with the Paryaya Table. The relational number should have a positive benefit, or positive property (good numbers are 2, 4, 6, 8, 9). It means that resonance is created.

The same comparisons need to be done with every birth star of every inhabitant of the space. If all birth stars are in a ‘good’ vibrational relationship, then the perimeter of the building can be used for construction.

Vaastu Purusha Mandala should be laid on the floor plan to determine the usage of building’s spaces.
