Several nodes created via Content templates in another node

Hello,

Have you some idea for view several nodes created via Content templates in another node?

I am using this code for view one Content template (node) in another node.
Which nodes I want to view, (created via Content templates), I can choose via NID.
$node = node_load(NID);
$body = node_view($node);
print $node->body;

Problem of this solution, which I want to solve, is that under this node I cant view nothing else.
Simply via this solution I cant view several nodes, (created via Content templates), in one node .

Have somebody better idea?

Thank you.
