Adding Node Reference to a Comment If I add a Node Reference field to a node content type (with Reference from URL as a widget,) this field appears in the rendered content and can be used to jump to the referenced node.

I am trying to get a similar result in the rendered comment of the same content type: If I add a Node Reference field with Reference to URL in the Comment Fields edit page of the content type, it doesn't show up in the rendered comment page.

Why do I want to do this? Because when one leaves a comment in the rendered content, a message is sent to the author of the post that a comment was posted. In the email, there is a link to see the comment. The link is of the form example.com/comment/000#comment-000 and that's not the original post with the comments below. 

So I am trying to add a link to the comment page that would send the reader to the rendered node where the comment was originally posted.

Does this mean one cannot reference a node from the same node's comment page?

Or does it mean there is another way to accomplish this?
You could achieve this with Comment Notify module.
We use it on few sites and it works great out of the box. 

From module page: 


  Features
  
  Mail registered and anonymous users about comment follow-ups
  
  Allow users to unsubscribe from notifications on a specific post with
  a single click
  
  Allow registered users to preset their follow-up setting in their
  profile
  
  Users can choose to get notifications about all comments on a node or
  just replies to their comment
  Registered authors can get notifications about comments on their nodes
  Note: Since it only notifies you about published comments, this is not a solution to notify admins when they need to moderate comments on their site
