Go Daan Puja, or Cow Donation Puja, is a sacred Vedic ritual that involves the donation of a cow, often accompanied by a calf, to a qualified Brahmin or temple. In Hindu tradition, the cow is revered as a symbol of selfless giving, abundance, and motherhood. Performing Go Daan is considered one of the highest forms of charity (daan) and is believed to bring immense spiritual merit (punya) to the donor.
