When Sri Caitanya Mahaprabhu visited Vrindavana, the cows and calves surrounded Him and began licking His body. All the cows relished the nectarean taste of His body and cried in ecstatic love. Seeing this, Lord Caitanya said, “Vraja has inconceivable qualities. The residents of Vraja all have natural devotion to Krishna.”
(Sri Advaita Prakasa, Chapter 16, by Sri Isana Nagara, trans. by Subhag Swami.)
Lord Caitanya then touched the cows with His lotus hand, and the cows all began to dance almost like gopis. Seeing the dancing of the cows, He was inundated with love. He chuckled and danced like an intoxicated person.
“In My last birth I was born in the family of cowherd men, and I gave protection to the calves and cows. Because of such pious activities, I have now become the son of a brāhmaṇa.”
Lord Caitanya in Śrī Caitanya Caritāmṛta Ādi 17.111
