Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Later [in the Eighth Canto of Srimad-Bhagavatam] I shall describe how Urukrama, Lord Vamanadeva, appeared as the son of the great sage Kasyapa and how He covered the three worlds with three steps. I shall describe the uncommon activities He performed, His qualities, His power and how He took birth from the womb of Aditi.
