reckon LH is mavis going completley gungho with somesort of ultimate fairy law type spell.I think Zeref wants her to be some sort of comrade/apprentice.As for the whole true meaning of life thing i reckon Zeref was just talking rubbish since he probably wanted her to come to him and ask her to seal him.I think her sin was trusting Zeref's advice/words.
