Enlightenment is always through surrender, but surrender is achieved through intelligence. Only idiots cannot surrender. To surrender you need great intelligence. To see the point of surrender is the climax of insight; to see the point that you are not separate from existence is the highest that intelligence can give to you.
Aristotle
Therefore the good man ought to be a lover of self, since he will then both benefit himself by acting nobly and aid his fellows; but the bad man ought not to be a lover of self, since he will follow his base passions, and so injure both himself and his neighbors. With the bad man therefore, what he does is not in accord with what he ought to do, but the good man does what he ought, since intelligence always chooses for itself that which is best, and the good man obeys his intelligence.
