Lord Vamana

Lord Vamana was the 12th son of Aditi By His own potency, the Supreme Personality of Godhead, who has multifarious potencies, appeared in the form of a dwarf as Urukrama, the twelfth son of Aditi. In the womb of His wife, whose name was Kirti, He begot one son, named Brihatsloka, who had many sons, headed by Saubhaga. SB 6.18.9: 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. http://www.vedabase.net/sb/6/18/en1
