Go puja is a very ancient Sanatana Dharma practice of worshipping cows, followed to this day by the Hindus. Kamadhenu is the cow believed to be with Lord Indra in the Swarglok. The name Kamadhenu means the one fulfilling desire or a wish. It is stated in the Vedas that all gods and goddesses including the Trinity reside in Kamadhenu. Therefore, all cows are venerated as the earthly embodiment of the Kamadhenu. Performing puja to cow and offering oblations are said to enhance the grace of gods and yield results quickly.
