Da'as Tevunos - Section 70

Said the Intellect - The heavenly intent, you have already heard, is only to give goodness to man, that he should gain merit through his actions with that which he rectifies in himself and completes his creation. And here is the matter of deficiency and completion which we mentioned above.
