We Indians have the ritual of greeting and treating our guests respectfully. If you go to any remote Indian village, you will find the villagers providing their guests with food and water. Even if they have nothing to eat for themselves they feed the guests first. This is our Indian custom and even the urban people follow it.
Serving is considered as a very important part of our Indian custom. As we know that cow is the holy animal of the Hindus, in our Indian scriptures, cow-service is very closely linked to the customs. Cow-service is a very crucial part of our Hindu customs as the animal is considered as our mother.
This is so because people consider that our God and Goddesses’ spirits reside in the body of a cow. That is the reason why people follow the belief that only when you feed a cow and take care of it, you indirectly service the almighty. This belief of indirectly servicing the God makes people happy.
