All Devis, Devatas, all pilgrimages and Lord Sri Hari Himself reside in the body of Go. Hence one can achieve anything by pleasing them through Goseva. It is said,
goshu bhaktascha labhate yat-yadicchati manavah ।
striyo′pi bhakta ya goshu ta ca kamamavapnuyuh ॥
putrarthi labhate putram kanyarthi tamavapnuyat ।
dhanarthi labhate vittam dharmarthi dharmamavapnuyat ॥
vidyarthi capnuyat vidyam sukharthi prapnuyat sukham ।
na kinchit durlabham chaiva gavam bhaktasya bharata ॥
