At the time of House Warming Ceremony Cow Pooja is Necessory one ?

Tamil Tradition and Culture is Healthy and Scientific Formalities to us

Why we do Cow Puja during House warming ceremony?

After the completion of Cow Pooja, the cow with its calf brought inside the house by keeping ulakkai (a lengthy wooden tool used for rice pounding) at the house entrance. 

If the cow and calf enter the house without any trouble, then the house is suitable for our living. 

Or, if the cow and calf frightened and refuse to enter the house, then we can decide that there is some thing wrong in that house and it is not suitable for living, because cow’s eyes can see the negative energies. 

As the presence of negative energies is dangerous, cow with its calf will not enter the house.  What a wonderful knowledge of our ancestors! Anything should be done after knowing, why we do so.
