How can I embed a node in a block?
create a block and use the below code to get the node body field content.

$node = node_load(YOUR_NODE_ID);
$body_content = $node-&gt;body[$node-&gt;language][0]['value'];
print $body_content;


If you are using a field other than body field, then you should print_r that $node variable and you will get all content type field relate with particular node.From this array you can get the all values created by content types.
