Translation:
The Lord appeared like a blackish cloud. He was dressed with yellow garments, His earrings shone on His ears like lightning, and His hair spread over His shoulders. He wore a garland of flowers, and His eyes were pinkish. With His strong, glorious arms, which award fearlessness throughout the universe, He took hold of Vāsuki and began churning the ocean, using Mandara Mountain as a churning rod. When engaged in this way, the Lord appeared like a beautifully situated mountain named Indranīla.
