In Vaastu Shastra, a set of six formulae called Aayadi are used to work out the Length, Breadth, perimeter, area and the height of the building. The six formulae are divided in to three sets and each set consists of two formulae. A specific set of formulae is used to work out the length, breadth and height of the building or the structure.

According to Vaastu Shastra, it is necessary that one follows the Aayadi formulae strictly in order to experience positive effects within the building.

AAYADI - DIMENSIONS:

Aayadi constitutes six formulae Aaya, Vyaya, Yoni, Raksha, Vara and Tithi. The remainder obtained by using these formulae, determines whether it is gain or loss. If it is a gain, then the structure is proportionate and stable and the dimensions are right. However if it is a loss, then it means the dimensions are not right and should be suitably corrected.

- Aaya- is the remainder obtained when Length is multiplied by 8 and divided by 12

- Raksha- is the remainder obtained when Length is multiplied by 8 and divided by 27

- Vyaaya- is the remainder obtained when Breadth is multiplied by 9 and divided by 10

- Yoni- is the remainder obtained when Breadth is multiplied by 3 and divided by 8

- Vara- is the remainder obtained when Height is multiplied by 9 and divided by 7

- Tithi- is the remainder obtained when Height is multiplied by 9 and divided by 30

FIXING LENGTH OF BUILDING/ROOMS:

- Aaya and Raksha formuale are used to fix both the Length of the building and of the rooms.

- Aaya also known as 'aadhayam', means income and 'Vyaya' means loss or expenditure. Therefore, the Aaya should always be greater than the Vyaya.

- Using the Aayadi formulae it has been concluded that for the Aaya to be more than the Vyaya the length of rooms/building should preferrably be 1.5 times the breadth or at least 1.375 times the width.

- This is why we find that sites are generally not square but rectangular with a Length 1.375 - 1.5 times the Breadth. For example: Sites have dimensions of 40 x 60, 30 x 40, 30 x 45, and 50 x 80.

FIXING THE BREADTH OF BUILDING/ROOMS:

- The Yoni and Vyaya formulae are used for fixing the breadth of the building.

- If the Yoni obtained is an odd remainder, then it is good whereas if it is even, then it is considered bad Yoni.

- 1, 3, 5 and 7 remainders are considered good Yoni and are associated with the directions East, South, West and North, respectively.

- Therefore depending on the direction the building faces, the corresponding Yoni should be used to fix the breadth of the building/rooms.

- The Yoni of the first floor should be the same as the Yoni of the ground floor.

- When an old house is being renovated, then a new Yoni different from the Yoni of the old house should be used for the renovated house.

- The Yoni formula defining the breadth measurement is useful for buildings that are not oriented to the cardinal directions.

- Vastu Shastra clearly emphasizes the importance of orienting buildings towards the four cardinal directions (North, East, South or West) so that they can withstand the impact of monsoon winds and natural energies and also benefit from them.

- As far as possible, buildings should not be oriented to the intermediate directions.

- But in rare situations, if the site faces an intermediate direction, the Yoni formula should be used so that the remainder is 1. This will ensure that the dimensions of the building are such that it can withstand the forces of nature.

- The height of the building can be fixed using the Vara and Tithi formulae.

- The height of the first floor should not be more than that of the Ground floor.

Dear Sir,

ReplyDeleteWhen I search Aayadi calculation on internet, I have a found your blog. Really it very useful and informative.

I try to calculate Aayadi for my proposed house plan, but I am not able to do it.

Please help me to calculate and give me your advise.

Thank you

Regards,

Gopal

Respected sir,

ReplyDeleteI had read ur article on house construction, very nice . I have started construction of my house, completed foundation, only now I have noticed the front width of the house is 34 feet but we are extending the car portico to the compound wall which makes it 37 feet. For calculating vastu for breadth which calculation should I take, should I make any other alterations as foundation has already been made?. KINDLY REPLY . If you would like I can send the floor plan of the house ,kindly give ur valuable advice

Thanx
