Nanda Maharaja was overwhelmed with jubliation when Lord Krishna appeared as his son. He arranged for a magnificent birth ceremony according to the Vedic regulations and invited brahmanas to recite Vedic mantras. He arranged for the worship of the demigods and forefathers and he gave two million cows, decorated with cloth and jewels, as well as seven hills of grain, in charity to the brahmanas. Summarized from Krishna Book, Chapter 5, Meeting of Nanda and Vasudeva
"The Vedic version says... that 'A spirit soul is by nature joyful'. Therefore—we are spirit soul—we are hankering after joy, where there is dance, where there is cinema, where there is nice food, where there is nice song, nice picture, nice beautiful woman or man. Everyone is searching after joy. Therefore the Supreme must be joyful."
