[Manish Jain]

Aayadi constitutes six formulae Aaya, Vyaya, Yoni, Raksha, Vara and Tithi which are explained below. The remainder obtained by using these formulae determines whether it is a 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.

1. Yoni is the remainder of  Breadth x 3 divided by 8
   
   
2. Vyaaya is the remainder of  Breadth x 9 divided by 10
   
   
3. Aaya is the remainder of  Length x 8 divided by 12
   
   
4. Raksha is the remainder of  Length x 8 divided by 27
   
   
5. Vara is the remainder of  Height x 9 divided by 7
   
   
6. Tithi is the remainder of  Height x 9 divided by 30
