Adam fell into the duality of the subject object relationship when he ate from the tree of the knowledge of good and evil, this much is implied in the very name of the tree which relates two opposing and irreconcilable terms. After eating from this tree, Adam began to see himself as seperate from God. This led to the absursity of his shame, since putting on clothes is not going to hide what's underneath from the all knowing being. For man, it is absurd that he sees himself as seperate from God, whose existence man depends on for his own being. Seeing his nakedness after having not seen it previously also speaks to man's mode of being shifting from the inward to the outward, with the surface of the body being the limit of outward development and the preoccupation with it being exposed pointing to this shift and fall. The two eyes of the two individuals, again signifying duality, being opened also attests to this shift since the eyes that see the nakedness can only see outwardly. And finally, recall that this shift from the inward to the outward is precisely the fall of man, since the "Kingdom of God is within you."
