I can understand that deformity of body still may make one live together with Dao, but deformity of De? Looks like a paradox to me! And not one of those intended paradoxes we see many times in the second part.
I am not sure why you are referring to Dao or the person De. This part is talking about a person called 支離疏 ( zhī lí shū ). Not a paradox, as I made my translation below, thanks to his deformity, he is lucky enough to finish out his life. That is my answer.
FYI:Translation by me ( whole part )
There is a person called 支離疏 ( zhī lí shū ). His backbone is bent and his chin is so long that it almost reaches his navel, his shoulder is so high that it is even above his head, his curled hair so high that it is pointing to the heaven. His armpit is like his thigh ( what?? by me ), his internal organs ( are so fat? ) so that they are above his head. If such a deformed person's job is sawing, washing, threshing, he is worth 10 people. The reason is, even if a war started, he can evade the conscription by his lord because of his deformity, can evade the duty of engineering works, so that he can relax while other 10 people must be engaged in war. Furthermore, he can receive 3鍾 ( Chinese measure ) of chestnuts and 10 bundle of woods as a mercy from his lord for poor folks and these deformed. Thanks to his deformation, he can live his life in peace, ( this part is my guess ), (even if his heart ( mind ) is different too) or ( even if a person's mind other than he is different ) ( I am not sure which is correct ), he is so lucky to finish his life ( in peace )!
I translated personally from Japanese one, so better way for you might be to go to Chinese site or Japanese ( a probable secondary source ) site for the meaning.
