drupal_render($node_view); is not working Node page is not loading once I add below code

 drupal_render($node_view);  


I was referring https://api.drupal.org/api/drupal/modules%21node%21node.module/function/node_view/7 
and added below code in my node--type.tpl.php

&lt;?php
  $node = node_load($nid);
  $node_view = node_view($node);
  $rendered_node = drupal_render($node_view);
  echo $rendered_node;
?&gt;
As I don't have the Drupal sources at hand right now, I didn't digg into it yet. But I'm pretty sure the node_view() function is using your node--type.tpl.php for rendering its output.

So calling it within your template will lead to a recursion. You might want to check on that.
