The cow is worshipped by Hindus as The wish - fulfilling cow.All the Gods are believed to reside in the body of cow.

Not only the cow provides us milk , ghee(clarified butter),dung for fuel,urine for medicine and many more but also as the source of all prosperity. The cow is the mother of mankind so Hindus calls her GAU MATA or KAMADHENU GAU.

Cow is the mother of all creatures. Cows are verily the mothers of the 33 crores of demi gods that administrate creation in the material existence throughout all universe. Cow is the goddess of the gods and refuge of all auspiciousness.Cows bestow every kind of happiness and for these reason they always are worshippable.

Lord Krishna also states in Srimad Bhagvad Gita(Chapter 10,Verse 28 ) about Kamdhenu cow-Among cow I am the wish fulfilling cow.

For these reasons Hindus worship the cow (GAU MATA) with this Aarti.
