Vastu Shastra

"When Inner Space and Outer Space resonate harmoniously, the result is a seamless blend of peace, vitality, health, prosperity, and creativity, manifesting effortlessly as the natural order."

"Ayadi calculations, Are a set of profound mathematical formulas within the realm of Vastu Shastra, have been utilized since ancient times for constructing Hindu temples and homes. By mastering their application, one can ascertain the precise cosmic vibration infused within every surrounding object. This knowledge empowers individuals to harmonize their living spaces and everyday objects with their birth nakshatra, enhancing their overall alignment and well-being."

The Motherwall:

The primary wall or container that facilitates the emergence of consciousness and the transformation of Vastu (unmanifest energy) into Vaastu (manifest energy) is referred to as the "Motherwall." In the context of a home, it typically encompasses the main four walls of the house, earning its name as it gives birth to the manifestation of Vaastu.

The Motherwall is meticulously constructed on a 9x9 grid, employing precise individualized measurements. These measurements imbue the central pada (module) with specific life-giving qualities that resonate throughout the entire structure. This form serves as a vessel for consciousness, Purusha, to assume its container's shape.

As a result, the dweller begins to vibrate in harmony with those same qualities, just like a tuning fork of one pitch causing another tuning fork of the same pitch in close proximity to vibrate. This resonance is achieved through the Ayadi calculations, a set of precise mathematical calculations chosen to align scientifically with the personal resonance and vibration of the dweller.

The Ayadi calculation takes into account various factors to determine the exact size of the Motherwall required to facilitate the dweller's experience of consciousness becoming conscious when entering and residing in a specific house. This information is crucial for fostering the complete effect of Vastu.

Once the Ayadi calculation is determined, the structure is divided into 9x9 modules, which can be square or rectangular. These modules serve as guidelines for locating significant features such as windows and doors along the appropriate grid lines. This maximizes the positive influence of the grid, solar energies, and cosmic energies. Additional rooms or extensions beyond the Motherwall can be added, but only in accordance with the mathematical formulas of Ayadi and the modules.

In essence, a house can be understood as a convergence of frequencies. A Vaastu or Mayonic house represents a convergence of well-defined frequencies determined by Ayadi. These frequencies bring forth spiritual peace, well-being, and happiness.

The Brahmasthan:

The Brahmasthan, located at the central module of the 9x9 grid formed by the Motherwall, serves as the focal point of the structure. It is the nucleus of space where consciousness becomes conscious and acts as the energy generator for the Vaastu building.

Similar to the nucleus of an atom, energetic forces revolve around the Brahmasthan. Its proper placement and design in harmony with the rest of the structure are crucial for breathing life into the building.

The Brahmasthan is an autocatalytic energy generator, meaning it generates energy based on the qualities and characteristics determined by the Ayadi calculation of the Motherwall. As mentioned earlier, these calculations determine the pulse and ultimate frequency of all the modules/padas, including the Brahmasthan. The walls that are appropriately positioned act as conduits for this energy.

The collective frequencies of all the modules and the Brahmasthan determine the vibrational frequency of the entire structure. The vibrational frequency generated by the Brahmasthan resonates within the body and consciousness of the dweller, influencing their experience.

It is important to note that some Vaastu consultants, who lack proper training, may attempt to "open the Brahmasthan" during rectification of non-Vaastu compliant houses. However, this is an improper use of Shastric knowledge. The qualities of a house are determined by the measurements of the main wall, its orientation on true east and true north, and other factors. Opening the Brahmasthan in a non-compliant house may amplify any negative traits caused by improper measurements and orientation, potentially bringing misfortune to the inhabitants.

Aayadi - Dimensions:

In Vaastu Shastra, the Aayadi formulae play a significant role in determining the dimensions of a building. These formulae consist of six components: Aaya, Vyaya, Yoni, Raksha, Vara, and Tithi. Adhering strictly to these formulae is believed to bring about positive effects within the structure.


The Aayadi formulae are utilized to calculate the Length, Breadth, perimeter, area, and height of the building. By applying these formulae, one can ascertain whether the dimensions are proportionate and stable, leading to favorable outcomes. Conversely, if the calculations yield a loss, it indicates that the dimensions need adjustment for optimal results.


Here are the six Aayadi formulae:


1.    Aaya: The remainder obtained when the Length is multiplied by 8 and divided by 12.

2.    Vyaaya: The remainder obtained when the Breadth is multiplied by 9 and divided by 10.

3.    Yoni: The remainder obtained when the Breadth is multiplied by 3 and divided by 8.

4.    Raksha: The remainder obtained when the Length is multiplied by 8 and divided by 27.

5.    Vara: The remainder obtained when the Height is multiplied by 9 and divided by 7.

6.    Tithi: The remainder obtained when the Height is multiplied by 9 and divided by 30.


By calculating these remainders, one can determine whether the dimensions of the building align with the prescribed guidelines. If any of the remainders indicate a loss, suitable corrections should be made to rectify the dimensions and ensure harmonious energy flow within the structure.

Fixing Length of Building/Rooms:

In the process of fixing the length of a building or rooms within it, the Aaya and Raksha formulae are utilized in Vaastu Shastra. Aaya, which translates to "income," and Vyaya, which means "expenditure" or "loss," are employed to ensure that the income (Aaya) is greater than the expenditure (Vyaya).


Using the Aayadi formulae, it has been determined that in order for the Aaya to surpass the Vyaya, the length of the rooms or the overall building should preferably be 1.5 times the breadth or at least 1.375 times the width.


As a result, it is common to find that building sites are rectangular rather than square, with lengths ranging from 1.375 to 1.5 times the breadth. For instance, site dimensions are often seen as 30 x 40, 30 x 45, 40 x 60 or 50 x 80.


By adhering to these recommendations, it is believed that the balance between income and expenditure is maintained, leading to favorable energies and harmonious living spaces according to Vaastu principles.

Fixing the Breadth of Building/Rooms:

When fixing the breadth of a building or rooms within it according to Vaastu Shastra, the Yoni and Vyaya formulae are employed. The Yoni formula helps determine the suitable breadth based on the direction the building faces.


In the Yoni formula, if the remainder obtained is odd, it is considered a good Yoni, while an even remainder is regarded as a bad Yoni. The remainders 1, 3, 5, and 7 are associated with the directions East, South, West, and North, respectively, and are considered good Yoni.


Depending on the direction the building faces, the corresponding Yoni should be used to determine the breadth of the building or rooms. For example, if the building faces East, a Yoni with a remainder of 1 should be used for fixing the breadth.


It is also important to note that the Yoni of the first floor should be the same as the Yoni of the ground floor. This ensures consistency and harmony throughout the building.


In the case of renovating an old house, if the renovation involves significant changes, a new Yoni different from the Yoni of the old house should be used for the renovated structure. This allows for a fresh alignment of energies and ensures the compatibility of the new design with Vaastu principles.


By considering the Yoni formula and aligning the breadth with the appropriate Yoni based on the building's direction, Vaastu proponents believe that the space can be optimized for positive energy flow and enhanced well-being.

Fixing the Dimensions on the Orientation:

In Vaastu Shastra, the preferred orientation for buildings is towards the four cardinal directions (North, East, South, or West). This alignment allows structures to benefit from natural energies and effectively withstand the impact of monsoon winds and other forces of nature.


The emphasis is on avoiding orientation towards intermediate directions whenever possible. However, in rare situations where the site faces an intermediate direction, the Yoni formula can be used to determine the breadth measurement. In such cases, it is recommended that the remainder obtained using the Yoni formula is 1.


By ensuring a remainder of 1, the dimensions of the building are adjusted to align with the principles of Vaastu Shastra, allowing it to better withstand the forces of nature and maintain harmony within the space.


While the cardinal directions are preferred, the Yoni formula provides a solution for situations where buildings are not optimally oriented. It is believed that by following these guidelines, the building can still benefit from the positive influences of natural energies and maintain stability and balance.

Units of Measurement in Vaastu Shastra:

Ayadi calculation is a set of six formulas used in Vastu Shastra to determine the dimensional conformance of a building. The six formulas are Aya, Vyaya, Yoni, Raksha, Vara, and Tithi. The perimeter of the building is the most important measure to create vibrational resonance of all involved energetic spaces. Ayadi is based on the numerical measures of wavelengths of OM Light (Light Energy) and OM Sound (Sound Energy). The perimeter of the primal energy particle, Paramanu, is measured and used as a proportional base in building's perimeter calculations. The perimeter is the measure of consciousness, which can be positive or negative. When using Ayadi, only positive measures (numbers) are used in the building construction. Ayadi is a technological application for building design and construction. The Ayadi calculation is the most influential element in the design and construction process. Using an Indian reference system, this calculation defines the interior perimeter of the structure, its proportions (either square or rectangular), the optimal location for the front door, the essential benefit to the owners (such as health, friendship, or prosperity), the precise size of every wall, door, and window, and other details.


calculations involving different aspects in Vastu Shastra:

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.

There are Several aspects to be examined under Ayadi and some of them are as listed below:

1. Aayam (Income) – Income / benefits

2. Vyaya (Expenditure) – Expenditure

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

4. Varam or Varaa (Day of a Week)– Weekdays

5. Nakshatra (Birth Star) – Star

6. Amsha (Quality) – Quality/feature

7. Ayu (lifespan) – Life of the building

The Process of calculation for each Ayadi

Financial problems can arise if Vyaya (Expenditure) exceeds Aaya (Income). Therefore, it is important to ensure that Aaya is always greater than Vyaya.

Ayadi Number of a Plot:

Ayadi number is a set of calculations used in Vastu Shastra to determine the dimensional conformance of a building. It is based on the perimeter of the property in the given Vastu unit, which is usually Hasta, a unit of measurement that equals 0.8382 meters or 2.75 feet. For example, a plot whose perimeter is 80 meters will have the Ayadi number 96 Hasta, which is the perimeter divided by the length of Hasta and rounded off to the nearest whole number. The Ayadi number is then used in various calculations to determine the suitability of the plot and its relationship with the owner

Nakshatra Calculation:

Nakshatra compatibility is an important factor in Vastu Shastra that determines the ruling Nakshatra star of the land and its relationship with the owner's Nakshatra. The Nakshatra of the land is calculated by the perimeter of the plot. It is believed that certain Nakshatras are compatible with certain directions, and if a person builds their home or office in a direction that is compatible with their birth star, they are more likely to experience success and good fortune.

However, it is important to note that exact Vastu principled property is excellent for everybody, and there is no need to find out the property direction as per the name or Rashi or Jathaka.


For calculating Aya and Vyaya:

In Vastu Shastra, Aya and Vyaya calculations are important in determining the suitability of a plot of land. The Aya calculation determines the Income Factor of the land, while the Vyaya calculation determines the Expense Factor of the Land. The Aya calculation is the remainder obtained when the length of the building is multiplied by 8 and divided by 12. Aya is also known as "aadhayam," which means “income”. The Vyaya calculation is the remainder obtained when the breadth of the building is multiplied by 9 and divided by 10. Vyaya means loss or expenditure. However, it is important to note that The Income Factor should be greater than the Expenditure Factor.

Yoni Calculation:

Yoni means a class or a category. Vastushastra defines eight categories or yonis, and all measurable size belong to one of these eight categories.

The Brahmasthaan – Brahmasthaan, which is the central point of a plot, always pulsates with cosmic energy and creates a flow of energy in the plot that begins to flow towards the edge of the plot. The flow of energy towards the cardinal directions constitutes four categories, and it's flow towards the corner directions constitute the other four categories.

Dhwaja Category (flagstaff) – Flow towards East

Simha Category (lion) – Flow towards South

Vrishabh Category (bull) – Flow towards West

Gaja Category (elephant) – Flow towards North

Dhoomra Category (smoke) – Flow towards South-East

Shwaan Category dog) – Flow towards South-West

Khar Category – Flow towards North-West

Kaak Category (crow) – Flow towards North-East

Of these categories the auspicious once are Dhwaja or Dhwajaya, Simha, Vrishabh and Gaja yonis are auspicious. Plots and houses whose dimensions confirm to these yonis enhance financial fortunes, good health, victory and success in competition, and overall prosperity.

Yonies to be best avoided are Dhoomra, Shwaan, Khar and Kaak as they are believed to enhance problems like ill health, bad fortunes, loss of money, failure in career, shattered happiness, fractured relationships etc.

Amsha Calculation:

The Amsham calculation serves to identify the land's inherent qualities. In accordance with the teachings of Maya in the Mayamatam treatise, there are eight Amsha’s, each representing distinct attributes:

1.    Thief

2.    Enjoyment

3.    Strength

4.    Riches

5.    Kingship

6.    Eunuch, powerless

7.    Fearless

8.    Troubles

9.    Prosperity

It is evident that plots characterized by Amshas of Bhukti, Shakti, Dhan, Nrupa, Abhaya, and Samriddhi are deemed favorable, as implied by their names.

Vara Calculation:

The Vara calculation plays a crucial role in assessing the property's compatibility with its owner. To determine the Vara of a property, one must perform the following calculations:

Multiply the property's Ayadi number by 9, and then divide the result by 7. The remainder obtained from this calculation represents the property's Vara.


There are seven Vara categories, each named after the days of the week, starting with 1 for Sunday and ending with 7 for Saturday. In this context, Vara 2, 4, 5, 6, and 7 are considered favorable, while Vara 1 and 3 are to be avoided. The avoidance of Vara 1 (Sunday) and 3 (Tuesday) is recommended due to their association with a higher likelihood of fire-related incidents on the property.

Vastu Calculations for Buildings

The extensive construction boom in major cities has raised questions about the correct application of Vastu Shastra-based building principles, mainly due to the complexity in architectural and construction methods. To effectively apply the various Vastu-based formulae, a clear understanding of the underlying concepts and significance is essential.


Vastu Calculations for Buildings, also known as Ayadi Shadvarga, are a set of six formulae employed by ancient wisdom masters. These formulae consist of Aya, Vyaya, Yoni, Rksha, Vara, and Tithi, and they are used to determine the dimensional conformance of a building. These six formulae are grouped into three sets, and each set comprises two formulae. Specific sets of formulae are used to determine the length, breadth, and height of a building or structure. The length and breadth correspond to the outer measurements of the foundation (bhumilamba) or its base (adhistana), while the height is measured from the bottom of the foundation or base to the highest point of the building. The results obtained from these formulae determine whether there is gain or loss, compatibility with constellations, and the lunar and solar days conducive to one's well-being.


Vastu Shastra places a strong emphasis on aligning constructions with the cardinal directions, specifically, north, east, south, or west. Whenever possible, buildings should face these cardinal directions, and angular orientations should be avoided. In rare situations where a site requires an angular orientation, the orientation (Yoni) formulae can be adjusted to yield a remainder of 1. The ancient masters understood the significance of factors such as monsoon winds and various energies, both physical and metaphysical, which were considered when orienting and constructing buildings.


The unit of measurement used is typically the Kisku Hasta, equivalent to 24 angulas. However, there are different regional interpretations of hasta measurements. One interpretation equates a hasta to two feet and nine inches, with an angula measuring 1 3/8th inches. Another interpretation considers a hasta to be 72 cm (28.3 inches) and an angula to be 3 cm (1.2 inches). A third interpretation defines a hasta as 18 inches (with an angula measuring 0.75 inches). In this context, a hasta is measured from the elbow to the tip of the middle finger.


Further research is needed to precisely define and standardize the Hasta measurement, whether it is 18 inches, 2.75 feet, 72 cm, or the actual arm length from the elbow or shoulder to the tip of the middle finger. As a guideline, a standard 18-inch Hasta measurement is often used when measuring from the elbow to the tip of the middle finger.

The Manasara recommends the determination of nine different lengths and breadths and five heights for a building. The Yoni formula, which defines the breadth measurement, underscores the importance of proper orientation. In ancient India and many other parts of the world, most religious buildings, palaces, cities, villages, and roads were aligned with the cardinal directions. Even iconic structures like the Giza and Great Pyramids of Egypt were oriented to the north.


In Indian Architecture, the standards of measurement are Angula (3/4th of an inch) and Hasta (18 inches). These measurements are categorized into six types, each with proportional ratios for various purposes:


1. Measurement of Height

2. Measurement of Breadth

3. Measurement of Width or Circumference

4. Measurement along Plumb Lines

5. Measurement of Thickness

6. Measurement of Interspace


Ratio of Height to Breadth:

The following height-to-breadth ratios are considered ideal for buildings, each indicating a specific aspect of beauty and proportion:


1. Ratio of 1: When the Height equals the Breadth, the structure is aesthetically proportionate.

2. Ratio of 1.25: When the Height is 1.25 times the Breadth, the structure is stable.

3. Ratio of 1.5: When the Height is 1.5 times the Breadth, the structure appears pleasant.

4. Ratio of 1.75: When the Height is 1.75 times the Breadth, the structure is both strong and beautiful.

5. Ratio of 2: When the Height is twice the Breadth, the structure appears gorgeous.


However, in contemporary construction, proportion and aesthetics are often overlooked, with a focus on maximizing Floor Area Ratio (F.A.R.) or Floor Space Index (F.S.I.), resulting in buildings that may lack proportion and aesthetic appeal. This is where a science like Vaastu Shastra can provide guidance to ensure proportions and aesthetics are maintained, as it offers formulae for creating beautiful houses.


Determining Aaya:

Aayas come in eight types: Dhvaja, Dhumra, Simha, Svana, Vrushabha, Khara, Gaja, and Kaka Yayasa. Each of these aayas corresponds to a specific direction, with some being considered beneficial for the native and others to be avoided. The effects of these aayas vary, such as monetary benefits, sorrows, luxuries, great sins, wealth and gains, success, or even death.


Vara (Weekdays):

The weekday on which a house is constructed is important. Sun and Mars in a house can result in a threat from fire, while other days are considered favorable.


Tithi (Lunar Day):

Tithis can also affect a house's fortunes. Rikta tithis may lead to poverty, and amavasya (new moon day) may cause diseases related to worms.



Among the 27 yogas, some are considered inauspicious and can lead to losses. Vratipat yoga can create a fear of death, and Vaidhruti yoga can result in various losses.


Ayuvu or Ayushu (Life Span):

The calculated life span of a house is significant. If it's more than 60 years, it is considered auspicious; if less than 60 years, it is inauspicious.


Dhana & Rina:

The number of Dhana (assets) should exceed the number of Rina (liabilities) according to prescribed mathematical calculations. The "pada" should be considered in all constructions.


Ashta Dikpatis (Lords of Directions):

Different "Dikpatis" or Lords of Directions have varying effects based on the remainder in calculations. For instance, Indra is considered good for women, Agni is associated with the threat of fire, Yama is inauspicious, Varuna increases cattle wealth, and so on.


To calculate Aayadi Nava Vargas, the "Kshetripada" or "Padam" is required, which represents the area for construction. By multiplying and dividing Kshetripada with specific numbers, you can derive nine vargas, including Aaya, Vara, Amsha, Dhana, Rina, Nakshatra, Tithe, Yoni, and Ayush. Different classical texts of Vastu Shastra may present these methods in slightly varied ways.

In Vastu Shastra, various methods are used to determine different aspects of a building's characteristics. Here are some of the methods and principles described:


Vishwakarma Prakasika Method:

1. Aaya: To calculate Aaya, multiply the Padam (length x width) by 9 and then divide it by 8.

2. Vara: To calculate Vara, multiply the Padam by 9 and divide it by 7.

3. Amsha: To calculate Amsha, multiply the Padam by 6 and divide it by 9.

4. Dravyam: To calculate Dravyam, multiply the Padam by 8 and divide it by 12.

5. Runa (Debts): To calculate Runa, multiply the Padam by 3 and divide it by 8.

6. Nakshatra: To calculate Nakshatra, multiply the Padam by 8 and divide it by 27.

7. Tithi: To calculate Tithi, multiply the Padam by 8 and divide it by 30.

8. Yuti/Yoga: To calculate Yuti or Yoga, multiply the Padam by 7 and divide it by 27.

9. Ayu (Life Span): To calculate Ayu, multiply the Padam by 8 and divide it by 120.


Kalamruta Method:

1. Dhanam (Income): Multiply the Padam by 8 and divide it by 12.

2. Runa (Debts): Multiply the Padam by 3 and divide it by 8.

3. Vara (The week): Multiply the Padam by 9 and divide it by 7.

4. Tithi: Multiply the Padam by 6 and divide it by 30.

5. Nakshatra: Multiply the Padam by 8 and divide it by 27.

6. Ayam: Multiply the Padam by 9 and divide it by 8.

7. Ayu (Life Span): Multiply the Padam by 9 and divide it by 120.

8. Amsha: Multiply the Padam by 6 and divide it by 8.

9. Dikruti: Multiply the Padam by 9 and divide it by 8.


In the Samrangana Sutradhara, King Bhoja provides further insights:


Aaya: To calculate Aaya, divide the Kshetripada (length x width) by 8. The remainder corresponds to specific aayas.

Nakshatra: Multiply the Kshetra pada by 8 and divide by 27. The remainder can indicate types of expenditure (vyaya).

Amsha Sadhana: Calculate by adding the number of vyaya and gruha nama nakshtra, then divide by 3 to get one of three Amshas: Indramasa, YamAmsha, or RajasAmsha. Each has different implications.

Rasi Sadhana: Multiply the gruha nakshatra by 4 and divide by 12 to determine the rasi. Certain rasas in relation to the native's rasi can be inauspicious.

Tarabala: Count the number of nakshatras from the Janma Nakshtra to the nakshatra of the house and divide by nine. The remainder can indicate auspicious, normal, or evil results.

Ayuvu (Longevity): Multiply the kshetra pada by 8 and divide by 120 to get the house's longevity. A remainder of 0 counts as 8, which is not considered good.


These methods provide guidelines for assessing different aspects of a building's characteristics in Vastu Shastra. It's important to consider these factors before constructing a building to achieve positive outcomes related to prosperity, wealth, and growth.
