“The word urukrama means ‘the one whose activities are glorious.’ Krama means ‘step.’ This word urukrama specifically indicates the Lord's incarnation as Vamana, who covered the whole universe by immeasurable steps. Lord Vishnu is powerful, and His activities are so glorious that He has created the spiritual world by His internal potency and the material world by His external potency.” (Shrila Prabhupada, Shrimad Bhagavatam, 1.7.10 Purport)
