People believe that if they do puja to the cows and “parikrama”(perambulations), then their wishes will be granted. It is said that all the gods are present in a cow. Cow milk is the food for Aswini Gods according to Rigveda. If there are many lizards in the house, sprinkling cow urine on the walls can drive them away. Modern science also accepted that the cow urine and feces have anti-microbial properties.
