Bhajan # 647 in the Premananda Bhajans book
Krishṇa, illusory Krishṇa, coloured blue like the sky, playing divine and magical dramas, You eat sand, then You eat white butter. Krishṇa of the cowherds, king of the Gōpīs, son of Nanda,You are always blissfully happy.
Bhajan # 654 in the Premananda Bhajans book
Enchanting flute player, child of Gokula, son of Nanda and Yashoda, who used to dance ecstatically with Radha. As a child You stole butter, just as You capture our hearts. You even attracted Cupid, the god of love. Great liberator, slayer of demons, You are knowledge.
