I am studying the NeichingTu diagram and your PDF file on the NeichingTu is very good.
After reading through Komjathy, Dr Yang Jwing Ming's books and Mantak Chia's discriptions. I have put together a selection of photocopied interpretations. I am writing to ask if you could remove the PDF security settings on this file so I can print it out and copy the text for research purposes.
