2. "A world of profit and delight, Of power, of honour, of omnipotence."-- These words describe the rewards that Faustus hopes to gain by pursuing forbidden knowledge. They suggest that the power and knowledge gained from studying the dark arts is worth the risk of damnation.
3. "All things that move between the quiet poles/ Shall be at my command. Emperors and kings,/ Are but obeyed in their several provinces,"-- This passage shows Faustus's ambition and desire for power. He wants to be able to control everything in the world, and he believes that forbidden knowledge will give him that power.
4. "Faustus, thou art damn'd; damned art thou, Faustus, damn'd!".-- This line comes at the end of the play, and it shows the ultimate consequences of Faustus's pursuit of forbidden knowledge. He has damned himself to hell for his actions, and there is no escape from his punishment.
