SB 8.6.33
tatas te mandara-girim
ojasotpatya durmadah
nadanta udadhim ninyuh
saktah parigha-bahavah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Thereafter, with great strength, the demons and demigods, who were all very powerful and who had long, stout arms, uprooted Mandara Mountain. Crying very loudly, they brought it toward the Ocean of Milk.
