You asked for https://nvcacademy.com/index.php?option=com_k2&view=item&id=695:theoretical-underpinnings-of-nvc-part-5&Itemid=439, and despite looking far and wide we could not find it. What may have happened?
the link you clicked to arrive here has a typo in it
or somehow we removed that page, or gave it another name
or, quite unlikely for sure, maybe you typed it yourself and there was a little typo?
