Easy Souls:

When Virgil appears near a save point, stand by him and press R. He will tell you a part of the story. Do it again, and he will say something else and give you Souls. Save the game, intentionally die, then continue from the save point. Talk to Virgil again to get more Souls. Repeat this as many times as desired.
