Madara's Ghost
<p>How was it exactly that Nagato came upon his Rinnegan?</p>

<p>Madara states that it was his, and that he gave it to him: how did he do that? Did he transplant it into Nagato, or did he transfer it otherwise?</p>

<p>Note: I do not recall whether this was explained in the manga or not.</p>
