SB 8.7.6

mathyamane ’rnave so ’drir
 anadharo hy apo ’visat
dhriyamano ’pi balibhir
 gauravat pandu-nandana
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O son of the Pandu dynasty, when Mandara Mountain was thus being used as a churning rod in the Ocean of Milk, it had no support, and therefore although held by the strong hands of the demigods and demons, it sank into the water.
